# Binding Reference
-## Structure for declaring binding
-### afb_binding_t
-
-The main structure, of type **afb_binding_t**, for describing the binding
-must be exported under the name **afbBindingExport**.
-
-This structure is defined as below.
-
-```C
-typedef struct afb_binding_v3 afb_binding_t;
-```
-
-Where:
-
-```C
-/**
- * Description of the bindings of type version 3
- */
-struct afb_binding_v3
-{
- /** api name for the binding, can't be NULL */
- const char *api;
-
- /** textual specification of the binding, can be NULL */
- const char *specification;
-
- /** some info about the api, can be NULL */
- const char *info;
-
- /** array of descriptions of verbs terminated by a NULL name, can be NULL */
- const struct afb_verb_v3 *verbs;
-
- /** callback at load of the binding */
- int (*preinit)(struct afb_api_x3 *api);
-
- /** callback for starting the service */
- int (*init)(struct afb_api_x3 *api);
-
- /** callback for handling events */
- void (*onevent)(struct afb_api_x3 *api, const char *event, struct json_object *object);
-
- /** userdata for afb_api_x3 */
- void *userdata;
-
- /** space separated list of provided class(es) */
- const char *provide_class;
-
- /** space separated list of required class(es) */
- const char *require_class;
-
- /** space separated list of required API(es) */
- const char *require_api;
-
- /** avoids concurrent requests to verbs */
- unsigned noconcurrency: 1;
-};
-```
-
-### struct afb_verb_t
-
-Each verb is described with a structure of type **afb_verb_t**
-defined below:
-
-```C
-typedef struct afb_verb_v3 afb_verb_t;
-```
-
-```C
-/**
- * Description of one verb as provided for binding API version 3
- */
-struct afb_verb_v3
-{
- /** name of the verb, NULL only at end of the array */
- const char *verb;
-
- /** callback function implementing the verb */
- void (*callback)(afb_req_t_x2 *req);
-
- /** required authorization, can be NULL */
- const struct afb_auth *auth;
-
- /** some info about the verb, can be NULL */
- const char *info;
-
- /**< data for the verb callback */
- void *vcbdata;
-
- /** authorization and session requirements of the verb */
- uint16_t session;
-
- /** is the verb glob name */
- uint16_t glob: 1;
-};
-```
-
-The **session** flags is one of the constant defined below:
-
-- AFB_SESSION_NONE : no flag, synonym to 0
-- AFB_SESSION_LOA_0 : Requires the LOA to be 0 or more, synonym to 0 or AFB_SESSION_NONE
-- AFB_SESSION_LOA_1 : Requires the LOA to be 1 or more
-- AFB_SESSION_LOA_2 : Requires the LOA to be 2 or more
-- AFB_SESSION_LOA_3 : Requires the LOA to be 3 or more
-- AFB_SESSION_CHECK : Requires the token to be set and valid
-- AFB_SESSION_REFRESH : Implies a token refresh
-- AFB_SESSION_CLOSE : Implies closing the session after request processed
-
-The LOA (Level Of Assurance) is set, by binding api, using the function **afb_req_session_set_LOA**.
-
-The session can be closed, by binding api, using the function **afb_req_session_close**.
-
-### afb_auth_t and afb_auth_type_t
-
-The structure **afb_auth_t** is used within verb description to
-set security requirements.
-The interpretation of the structure depends on the value of the field **type**.
-
-```C
-typedef struct afb_auth afb_auth_t;
-
-/**
- * Definition of an authorization entry
- */
-struct afb_auth
-{
- /** type of entry @see afb_auth_type */
- enum afb_auth_type type;
-
- union {
- /** text when @ref type == @ref afb_auth_Permission */
- const char *text;
-
- /** level of assurancy when @ref type == @ref afb_auth_LOA */
- unsigned loa;
-
- /** first child when @ref type in { @ref afb_auth_Or, @ref afb_auth_And, @ref afb_auth_Not } */
- const struct afb_auth *first;
- };
-
- /** second child when @ref type in { @ref afb_auth_Or, @ref afb_auth_And } */
- const struct afb_auth *next;
-};
-
-```
-
-The possible values for **type** is defined here:
-
-```C
-typedef enum afb_auth_type afb_auth_type_t;
-
-/**
- * Enumeration for authority (Session/Token/Assurance) definitions.
- *
- * @see afb_auth
- */
-enum afb_auth_type
-{
- /** never authorized, no data */
- afb_auth_No = 0,
-
- /** authorized if token valid, no data */
- afb_auth_Token,
-
- /** authorized if LOA greater than data 'loa' */
- afb_auth_LOA,
-
- /** authorized if permission 'text' is granted */
- afb_auth_Permission,
-
- /** authorized if 'first' or 'next' is authorized */
- afb_auth_Or,
-
- /** authorized if 'first' and 'next' are authorized */
- afb_auth_And,
-
- /** authorized if 'first' is not authorized */
- afb_auth_Not,
-
- /** always authorized, no data */
- afb_auth_Yes
-};
-```
-
-Example:
-
-```C
-static const afb_auth_t myauth[] = {
- { .type = afb_auth_Permission, .text = "urn:AGL:permission:me:public:set" },
- { .type = afb_auth_Permission, .text = "urn:AGL:permission:me:public:get" },
- { .type = afb_auth_Or, .first = &myauth[1], .next = &myauth[0] }
-};
-```
-
-## Functions of class afb_daemon
-
-The 3 following functions are linked to libsystemd.
-They allow use of **sd_event** features and access
-to **sd_bus** features.
-
-```C
-/*
- * Retrieves the common systemd's event loop of AFB
- *
- */
-struct sd_event *afb_daemon_get_event_loop();
-
-/*
- * Retrieves the common systemd's user/session d-bus of AFB if active
- */
-struct sd_bus *afb_daemon_get_user_bus();
-
-/*
- * Retrieves the common systemd's system d-bus of AFB if active or NULL
- */
-struct sd_bus *afb_daemon_get_system_bus();
-```
-
-The 2 following functions are linked to event management.
-Broadcasting an event send it to any possible listener.
-
-```C
-/*
- * Broadcasts widely the event of 'name' with the data 'object'.
- * 'object' can be NULL.
- *
- * For convenience, the function calls 'json_object_put' for 'object'.
- * Thus, in the case where 'object' should remain available after
- * the function returns, the function 'json_object_get' shall be used.
- *
- * Calling this function is only forbidden during preinit.
- *
- * Returns the count of clients that received the event.
- */
-int afb_daemon_broadcast_event(const char *name, struct json_object *object);
-
-/*
- * Creates an event of 'name' and returns it.
- *
- * Calling this function is only forbidden during preinit.
- *
- * See afb_event_is_valid to check if there is an error.
- */
-afb_event_t afb_daemon_make_event(const char *name);
-```
-
-The following function is used by logging macros and should normally
-not be used.
-Instead, you should use the macros:
-
-- **AFB\_ERROR**
-- **AFB\_WARNING**
-- **AFB\_NOTICE**
-- **AFB\_INFO**
-- **AFB\_DEBUG**
-
-```C
-/*
- * Send a message described by 'fmt' and following parameters
- * to the journal for the verbosity 'level'.
- *
- * 'file', 'line' and 'func' are indicators of position of the code in source files
- * (see macros __FILE__, __LINE__ and __func__).
- *
- * 'level' is defined by syslog standard:
- * EMERGENCY 0 System is unusable
- * ALERT 1 Action must be taken immediately
- * CRITICAL 2 Critical conditions
- * ERROR 3 Error conditions
- * WARNING 4 Warning conditions
- * NOTICE 5 Normal but significant condition
- * INFO 6 Informational
- * DEBUG 7 Debug-level messages
- */
-void afb_daemon_verbose(int level, const char *file, int line, const char * func, const char *fmt, ...);
-```
-
-The 2 following functions MUST be used to access data of the bindings.
-
-```C
-/*
- * Get the root directory file descriptor. This file descriptor can
- * be used with functions 'openat', 'fstatat', ...
- */
-int afb_daemon_rootdir_get_fd();
-
-/*
- * Opens 'filename' within the root directory with 'flags' (see function openat)
- * using the 'locale' definition (example: "jp,en-US") that can be NULL.
- * Returns the file descriptor or -1 in case of error.
- */
-int afb_daemon_rootdir_open_locale(const char *filename, int flags, const char *locale);
-```
-
-The following function is used to queue jobs.
-
-```C
-/*
- * Queue the job defined by 'callback' and 'argument' for being executed asynchronously
- * in this thread (later) or in an other thread.
- * If 'group' is not NUL, the jobs queued with a same value (as the pointer value 'group')
- * are executed in sequence in the order of there submission.
- * If 'timeout' is not 0, it represent the maximum execution time for the job in seconds.
- * At first, the job is called with 0 as signum and the given argument.
- * The job is executed with the monitoring of its time and some signals like SIGSEGV and
- * SIGFPE. When a such signal is catched, the job is terminated and re-executed but with
- * signum being the signal number (SIGALRM when timeout expired).
- *
- * Returns 0 in case of success or -1 in case of error.
- */
-int afb_daemon_queue_job(void (*callback)(int signum, void *arg), void *argument, void *group, int timeout)
-```
-
-The following function must be used when a binding depends on other
-bindings at its initialization.
-
-```C
-/*
- * Tells that it requires the API of "name" to exist
- * and if 'initialized' is not null to be initialized.
- * Calling this function is only allowed within init.
- * Returns 0 in case of success or -1 in case of error.
- */
-int afb_daemon_require_api(const char *name, int initialized)
-```
-
-This function allows to give a different name to the binding.
-It can be called during pre-init.
-
-```C
-/*
- * Set the name of the API to 'name'.
- * Calling this function is only allowed within preinit.
- * Returns 0 in case of success or -1 in case of error.
- */
-int afb_daemon_rename_api(const char *name);
-```
-
-## Functions of class afb_service
-
-The following functions allow services to call verbs of other
-bindings for themselves.
-
-```C
-/**
- * Calls the 'verb' of the 'api' with the arguments 'args' and 'verb' in the name of the binding.
- * The result of the call is delivered to the 'callback' function with the 'callback_closure'.
- *
- * For convenience, the function calls 'json_object_put' for 'args'.
- * Thus, in the case where 'args' should remain available after
- * the function returns, the function 'json_object_get' shall be used.
- *
- * The 'callback' receives 3 arguments:
- * 1. 'closure' the user defined closure pointer 'callback_closure',
- * 2. 'status' a status being 0 on success or negative when an error occured,
- * 2. 'result' the resulting data as a JSON object.
- *
- * @param api The api name of the method to call
- * @param verb The verb name of the method to call
- * @param args The arguments to pass to the method
- * @param callback The to call on completion
- * @param callback_closure The closure to pass to the callback
- *
- * @see also 'afb_req_subcall'
- */
-void afb_service_call(
- const char *api,
- const char *verb,
- struct json_object *args,
- void (*callback)(void*closure, int status, struct json_object *result),
- void *callback_closure);
-
-/**
- * Calls the 'verb' of the 'api' with the arguments 'args' and 'verb' in the name of the binding.
- * 'result' will receive the response.
- *
- * For convenience, the function calls 'json_object_put' for 'args'.
- * Thus, in the case where 'args' should remain available after
- * the function returns, the function 'json_object_get' shall be used.
- *
- * @param api The api name of the method to call

- * @returns 0 in case of success or a negative value in case of error.
- *
- * @see also 'afb_req_subcall'
- */
-int afb_service_call_sync(
- const char *api,
- const char *verb,
- struct json_object *args,
- struct json_object **result);
-```
-
-## Functions of class afb_event
-
-This function checks whether the event is valid.
-It must be used when creating events.
-
-```C
-/*
- * Checks wether the 'event' is valid or not.
- *
- * Returns 0 if not valid or 1 if valid.
- */
-int afb_event_is_valid(afb_event_t event);
-```
-
-The two following functions are used to broadcast or push
-event with its data.
-
-```C
-/*
- * Broadcasts widely the 'event' with the data 'object'.
- * 'object' can be NULL.

+
+For the migration, it is enough to just add the new argument without
+using it.
+
+Consider use of the new reply
+-----------------------------
+
+The v3 allows error reply with JSON object. To achieve it, an unified
+reply function's family is introduced:
+
+```C
+void afb_req_reply(afb_req_t req, json_object *obj, const char *error, const char *info);
+void afb_req_reply_v(afb_req_t req, json_object *obj, const char *error, const char *info, va_list args);
+void afb_req_reply_f(afb_req_t req, json_object *obj, const char *error, const char *info, ...);
+```
+
+The functions **success** and **fail** are still supported.
+These functions are now implemented as the following macros:
+
+
+```C
+#define afb_req_success(r,o,i) afb_req_reply(r,o,NULL,i)
+#define afb_req_success_f(r,o,...) afb_req_reply_f(r,o,NULL,__VA_ARGS__)
+#define afb_req_success_v(r,o,f,v) afb_req_reply_v(r,o,NULL,f,v)
+#define afb_req_fail(r,e,i) afb_req_reply(r,NULL,e,i)
+#define afb_req_fail_f(r,e,...) afb_req_reply_f(r,NULL,e,__VA_ARGS__)
+#define afb_req_fail_v(r,e,f,v) afb_req_reply_v(r,NULL,e,f,v)
+```
+
+This is a decision of the developer to switch to the new family
+**afb_req_reply** or to keep the good old functions **afb_req_fail**
+adn **afb_req_success**.
+
+Consider use of the new (sub)call
+---------------------------------
+
+The new call and subcall (the functions **afb_api_call**, **afb_api_call_sync**,
+**afb_req_subcall** and **afb_req_subcall_sync**) functions are redesigned
+to better fit the new reply behaviour. In most case the developer will benefit
+of the new behavior that directly gives result and error without enforcing
+to parse the JSON object result.
+
+The subcall functions are also fully redesigned to allow precise handling
+of the context and event subscriptions. The new design allows you to specify:
+
+ - whether the subcall is made in the session of the caller or in the session
+ of the service
+ - whether the credentials to use are those of the caller or those of the
+ service
+ - whether the caller or the service or both or none will receive the
+ eventually events during the subcall.
+
+See [calls](reference-v3/func-api/#calls-and-job-functions) and
+[subcalls](reference-v3/func-req/#subcall-functions).

+==========================
+
+# Structure for declaring binding
+---------------------------------
+
+### struct afb_binding_v2
+
+The main structure, of type **afb_binding_v2**, for describing the binding
+must be exported under the name **afbBindingV2**.
+
+This structure is defined as below.
+
+```C
+/*
+ * Description of the bindings of type version 2
+ */
+struct afb_binding_v2
+{
+ const char *api; /* api name for the binding */
+ const char *specification; /* textual openAPIv3 specification of the binding */
+ const char *info; /* some info about the api, can be NULL */
+ const struct afb_verb_v2 *verbs; /* array of descriptions of verbs terminated by a NULL name */
+ int (*preinit)(); /* callback at load of the binding */
+ int (*init)(); /* callback for starting the service */
+ void (*onevent)(const char *event, struct json_object *object); /* callback for handling events */
+ unsigned noconcurrency: 1; /* avoids concurrent requests to verbs */
+};
+```
+
+### struct afb_verb_v2
+
+Each verb is described with a structure of type **afb_verb_v2**
+defined below:
+
+```C
+/*
+ * Description of one verb of the API provided by the binding
+ * This enumeration is valid for bindings of type version 2
+ */
+struct afb_verb_v2
+{
+ const char *verb; /* name of the verb */
+ void (*callback)(struct afb_req req); /* callback function implementing the verb */
+ const struct afb_auth *auth; /* required authorization */
+ const char *info; /* some info about the verb, can be NULL */
+ uint32_t session; /* authorization and session requirements of the verb */
+};
+```
+
+The **session** flags is one of the constant defined below:
+
+- AFB_SESSION_NONE : no flag, synonym to 0
+- AFB_SESSION_LOA_0 : Requires the LOA to be 0 or more, synonym to 0 or AFB_SESSION_NONE
+- AFB_SESSION_LOA_1 : Requires the LOA to be 1 or more
+- AFB_SESSION_LOA_2 : Requires the LOA to be 2 or more
+- AFB_SESSION_LOA_3 : Requires the LOA to be 3 or more
+- AFB_SESSION_CHECK : Requires the token to be set and valid
+- AFB_SESSION_REFRESH : Implies a token refresh
+- AFB_SESSION_CLOSE : Implies cloing the session
+
+The LOA (Level Of Assurance) is set, by binding, using the function **afb_req_session_set_LOA**.
+
+### struct afb_auth and enum afb_auth_type
+
+The structure **afb_auth** is used within verb description to
+set security requirements.
+The interpretation of the structure depends on the value of the field **type**.
+
+```C
+struct afb_auth
+{
+ const enum afb_auth_type type;
+ union {
+ const char *text;
+ const unsigned loa;
+ const struct afb_auth *first;
+ };
+ const struct afb_auth *next;
+};
+```
+
+The possible values for **type** is defined here:
+
+```C
+/*
+ * Enum for Session/Token/Assurance middleware.
+ */
+enum afb_auth_type
+{
+ afb_auth_No = 0, /** never authorized, no data */
+ afb_auth_Token, /** authorized if token valid, no data */
+ afb_auth_LOA, /** authorized if LOA greater than data 'loa' */
+ afb_auth_Permission, /** authorized if permission 'text' is granted */
+ afb_auth_Or, /** authorized if 'first' or 'next' is authorized */
+ afb_auth_And, /** authorized if 'first' and 'next' are authorized */
+ afb_auth_Not, /** authorized if 'first' is not authorized */
+ afb_auth_Yes /** always authorized, no data */
+};
+```
+
+Example:
+
+```C
+static const struct afb_auth _afb_auths_v2_monitor[] = {
+ { .type = afb_auth_Permission, .text = "urn:AGL:permission:monitor:public:set" },
+ { .type = afb_auth_Permission, .text = "urn:AGL:permission:monitor:public:get" },
+ { .type = afb_auth_Or, .first = &_afb_auths_v2_monitor[1], .next = &_afb_auths_v2_monitor[0] }
+};
+```
+
+## Functions of class afb_daemon
+
+The 3 following functions are linked to libsystemd.
+They allow use of **sd_event** features and access
+to **sd_bus** features.
+
+```C
+/*
+ * Retrieves the common systemd's event loop of AFB
+ */
+struct sd_event *afb_daemon_get_event_loop();
+
+/*
+ * Retrieves the common systemd's user/session d-bus of AFB
+ */
+struct sd_bus *afb_daemon_get_user_bus();
+
+/*
+ * Retrieves the common systemd's system d-bus of AFB
+ */
+struct sd_bus *afb_daemon_get_system_bus();
+```
+
+The 2 following functions are linked to event management.
+Broadcasting an event send it to any possible listener.
+
+```C
+/*
+ * Broadcasts widely the event of 'name' with the data 'object'.
+ * 'object' can be NULL.
+ *
+ * For convenience, the function calls 'json_object_put' for 'object'.
+ * Thus, in the case where 'object' should remain available after
+ * the function returns, the function 'json_object_get' shall be used.
+ *
+ * Calling this function is only forbidden during preinit.
+ *
+ * Returns the count of clients that received the event.
+ */
+int afb_daemon_broadcast_event(const char *name, struct json_object *object);
+
+/*
+ * Creates an event of 'name' and returns it.
+ *
+ * Calling this function is only forbidden during preinit.
+ *
+ * See afb_event_is_valid to check if there is an error.
+ */
+struct afb_event afb_daemon_make_event(const char *name);
+```
+
+The following function is used by logging macros and should normally
+not be used.
+Instead, you should use the macros:
+
+- **AFB\_ERROR**
+- **AFB\_WARNING**
+- **AFB\_NOTICE**
+- **AFB\_INFO**
+- **AFB\_DEBUG**
+
+```C
+/*
+ * Send a message described by 'fmt' and following parameters
+ * to the journal for the verbosity 'level'.
+ *
+ * 'file', 'line' and 'func' are indicators of position of the code in source files
+ * (see macros __FILE__, __LINE__ and __func__).
+ *
+ * 'level' is defined by syslog standard:
+ * EMERGENCY 0 System is unusable
+ * ALERT 1 Action must be taken immediately
+ * CRITICAL 2 Critical conditions
+ * ERROR 3 Error conditions
+ * WARNING 4 Warning conditions
+ * NOTICE 5 Normal but significant condition
+ * INFO 6 Informational
+ * DEBUG 7 Debug-level messages
+ */
+void afb_daemon_verbose(int level, const char *file, int line, const char * func, const char *fmt, ...);
+```
+
+The 2 following functions MUST be used to access data of the bindings.
+
+```C
+/*
+ * Get the root directory file descriptor. This file descriptor can
+ * be used with functions 'openat', 'fstatat', ...
+ */
+int afb_daemon_rootdir_get_fd();
+
+/*
+ * Opens 'filename' within the root directory with 'flags' (see function openat)
+ * using the 'locale' definition (example: "jp,en-US") that can be NULL.
+ * Returns the file descriptor or -1 in case of error.
+ */
+int afb_daemon_rootdir_open_locale(const char *filename, int flags, const char *locale);
+```
+
+The following function is used to queue jobs.
+
+```C
+/*
+ * Queue the job defined by 'callback' and 'argument' for being executed asynchronously
+ * in this thread (later) or in an other thread.
+ * If 'group' is not NUL, the jobs queued with a same value (as the pointer value 'group')
+ * are executed in sequence in the order of there submission.
+ * If 'timeout' is not 0, it represent the maximum execution time for the job in seconds.
+ * At first, the job is called with 0 as signum and the given argument.
+ * The job is executed with the monitoring of its time and some signals like SIGSEGV and
+ * SIGFPE. When a such signal is catched, the job is terminated and re-executed but with
+ * signum being the signal number (SIGALRM when timeout expired).
+ *
+ * Returns 0 in case of success or -1 in case of error.
+ */
+int afb_daemon_queue_job(void (*callback)(int signum, void *arg), void *argument, void *group, int timeout)
+```
+
+The following function must be used when a binding depends on other
+bindings at its initialization.
+
+```C
+/*
+ * Tells that it requires the API of "name" to exist
+ * and if 'initialized' is not null to be initialized.
+ * Calling this function is only allowed within init.
+ * Returns 0 in case of success or -1 in case of error.
+ */
+int afb_daemon_require_api(const char *name, int initialized)
+```
+
+This function allows to give a different name to the binding.
+It can be called during pre-init.
+
+```C
+/*
+ * Set the name of the API to 'name'.
+ * Calling this function is only allowed within preinit.
+ * Returns 0 in case of success or -1 in case of error.
+ */
+int afb_daemon_rename_api(const char *name);
+```
+
+## Functions of class afb_service
+
+The following functions allow services to call verbs of other
+bindings for themselves.
+
+```C
+/**
+ * Calls the 'verb' of the 'api' with the arguments 'args' and 'verb' in the name of the binding.
+ * The result of the call is delivered to the 'callback' function with the 'callback_closure'.
+ *
+ * For convenience, the function calls 'json_object_put' for 'args'.
+ * Thus, in the case where 'args' should remain available after
+ * the function returns, the function 'json_object_get' shall be used.
+ *
+ * The 'callback' receives 3 arguments:
+ * 1. 'closure' the user defined closure pointer 'callback_closure',
+ * 2. 'status' a status being 0 on success or negative when an error occurred,
+ * 2. 'result' the resulting data as a JSON object.
+ *
+ * @param api The api name of the method to call
+ * @param verb The verb name of the method to call
+ * @param args The arguments to pass to the method
+ * @param callback The to call on completion
+ * @param callback_closure The closure to pass to the callback
+ *
+ * @see also 'afb_req_subcall'
+ */
+void afb_service_call(
+ const char *api,
+ const char *verb,
+ struct json_object *args,
+ void (*callback)(void*closure, int status, struct json_object *result),
+ void *callback_closure);
+
+/**
+ * Calls the 'verb' of the 'api' with the arguments 'args' and 'verb' in the name of the binding.
+ * 'result' will receive the response.
+ *
+ * For convenience, the function calls 'json_object_put' for 'args'.
+ * Thus, in the case where 'args' should remain available after

+ */
+int afb_service_call_sync(
+ const char *api,
+ const char *verb,
+ struct json_object *args,
+ struct json_object **result);
+```
+
+## Functions of class afb_event
+
+This function checks whether the event is valid.
+It must be used when creating events.
+
+```C
+/*
+ * Checks wether the 'event' is valid or not.
+ *
+ * Returns 0 if not valid or 1 if valid.
+ */
+int afb_event_is_valid(struct afb_event event);
+```
+
+The two following functions are used to broadcast or push
+event with its data.
+
+```C
+/*
+ * Broadcasts widely the 'event' with the data 'object'.
+ * 'object' can be NULL.
+ *
+ * For convenience, the function calls 'json_object_put' for 'object'.
+ * Thus, in the case where 'object' should remain available after
+ * the function returns, the function 'json_object_get' shall be used.

+
+/*

+ *
+ * Returns the count of clients that received the event.
+ */
+int afb_event_push(struct afb_event event, struct json_object *object);
+```
+
+The following function destroys the event.
+
+```C
+/*
+ * Drops the data associated to the 'event'
+ * After calling this function, the event
+ * MUST NOT BE USED ANYMORE.
+ */
+void afb_event_drop(struct afb_event event);
+```
+
+This function allows to retrieve the exact name of the event.
+
+```C
+/*
+ * Gets the name associated to the 'event'.
+ */
+const char *afb_event_name(struct afb_event event);
+```

+## Logging macros
+
+The following macros must be used for logging:
+
+```C
+AFB_ERROR(fmt,...)
+AFB_WARNING(fmt,...)
+AFB_NOTICE(fmt,...)
+AFB_INFO(fmt,...)
+AFB_DEBUG(fmt,...)
+```
+
+The following macros can be used for logging in the context
+of a request **req** of type **afb_req**:
+
+```C
+AFB_REQ_ERROR(req,fmt,...)
+AFB_REQ_WARNING(req,fmt,...)
+AFB_REQ_NOTICE(req,fmt,...)
+AFB_REQ_INFO(req,fmt,...)
+AFB_REQ_DEBUG(req,fmt,...)
+```
+
+By default, the logging macros add file, line and function
+indication.

+The websocket protocol x-afb-ws-json1
+=====================================
+
+The WebSocket protocol *x-afb-ws-json1* is used to communicate between
+an application and a binder. It allows access to all registered apis
+of the binder.
+
+This protocol is inspired from the protocol **OCPP - SRPC** as described for
+example here:
+[OCPP transport specification - SRPC over WebSocket](http://www.gir.fr/ocppjs/ocpp_srpc_spec.shtml).
+
+The registration to the IANA is still to be done, see:
+[WebSocket Protocol Registries](https://www.iana.org/assignments/websocket/websocket.xml)
+
+This document gives a short description of the protocol *x-afb-ws-json1*.
+A more formal description has to be done.
+
+
+Architecture
+------------
+
+The protocol is intended to be symmetric. It allows:
+
+ - to CALL a remote procedure that returns a result
+ - to push and receive EVENT
+
+
+Messages
+--------
+
+Valid messages are made of *text* frames that are all valid JSON.
+
+Valid messages are:
+
+Calls:
+```
+[ 2, ID, PROCN, ARGS ]
+[ 2, ID, PROCN, ARGS, TOKEN ]
+```
+
+Replies (3: OK, 4: ERROR):
+```
+[ 3, ID, RESP ]
+[ 3, ID, RESP, TOKEN ]
+[ 4, ID, RESP ]
+[ 4, ID, RESP, TOKEN ]
+```
+
+Events:
+```
+[ 5, EVTN, OBJ ]
+```
+
+Where:
+
+| Field | Type | Description
+|-------|--------|------------------
+| ID | string | A string that identifies the call. A reply to that call use the ID of the CALL.
+| PROCN | string | The procedure name to call of the form "api/verb"
+| ARGS | any | Any argument to pass to the call (see afb_req_json that returns it)
+| RESP | any | The response to the call
+| TOKEN | string | The token in case of refresh
+| EVTN | string | Name of the event in the form "api/event"
+| OBJ | any | The companion object of the event
+
+Below, an example of exchange:
+
+```
+C->S: [2,"156","hello/ping",null]
+S->C: [3,"156",{"response":"Some String","jtype":"afb-reply","request":{"status":"success","info":"Ping Binder Daemon tag=pingSample count=1 query=\"null\"","uuid":"ec30120c-6997-4529-9d63-c0de0cce56c0"}}]
+```
+
+
+Future
+------
+
+Here are the planned extensions:
+
+ - add binary messages with cbor data
+ - add calls with unstructured replies
+
+This could be implemented by extending the current protocol or by
+allowing the binder to accept either protocol including the new ones.
+
+
+Javascript implementation
+-------------------------
+
+The file **AFB.js** is a javascript implementation of the protocol.
+
+Here is that code:

+Macro for logging
+=================
+
+The final behaviour of macros can be tuned using 2 defines that must be defined
+before including **<afb/afb-binding.h>**.
+
+| define | action
+|---------------------------------------|--------------------
+| AFB_BINDING_PRAGMA_NO_VERBOSE_DATA | show file and line, remove function and text message
+| AFB_BINDING_PRAGMA_NO_VERBOSE_DETAILS | show text, remove function, line and file
+
+## Logging for an api
+
+The following macros must be used for logging for an **api** of type
+**afb_api_t**.
+
+```C
+AFB_API_ERROR(api,fmt,...)
+AFB_API_WARNING(api,fmt,...)
+AFB_API_NOTICE(api,fmt,...)
+AFB_API_INFO(api,fmt,...)
+AFB_API_DEBUG(api,fmt,...)
+```
+
+## Logging for a request
+
+
+The following macros can be used for logging in the context
+of a request **req** of type **afb_req_t**:
+
+```C
+AFB_REQ_ERROR(req,fmt,...)
+AFB_REQ_WARNING(req,fmt,...)
+AFB_REQ_NOTICE(req,fmt,...)
+AFB_REQ_INFO(req,fmt,...)
+AFB_REQ_DEBUG(req,fmt,...)
+```
+
+By default, the logging macros add file, line and function
+indication.
+
+## Logging legacy
+
+The following macros are provided for legacy.
+
+```C
+AFB_ERROR(fmt,...)
+AFB_WARNING(fmt,...)
+AFB_NOTICE(fmt,...)
+AFB_INFO(fmt,...)
+AFB_DEBUG(fmt,...)
+```

+# Types and globals
+
+## The global afbBindingRoot
+
+The global **afbBindingRoot** of type **afb_api_t** is always implicitely
+defined for bindings of version 3 or upper. It records the root api of
+the binding.
+
+When the binding has a defined **afbBindingExport**, the root api
+**afbBindingRoot** is the **afb_pi_t** relative to the api created for
+this static description.
+
+When the binding has no defined **afbBindingExport**, the root api is
+a virtual api representing the shared object of the binding. In that case
+the name of the api is the path of the shared object. Its use is restricted
+but allows log messages.
+
+## The global afbBindingExport
+
+The global **afbBindingExport** is not mandatory.
+
+If **afbBindingExport** is defined and exported, it must be of the type
+**const afb_binding_t** and must describe the *root* api of the binding.
+
+## The type afb_api_t
+
+Bindings now can declare more than one api. The counter part is that
+a new handle is needed to manage apis. These handles are of the type
+**afb_api_t**.
+
+It is defined as below.
+
+```C
+typedef struct afb_api_x3 afb_api_t;
+```
+
+## The type afb_binding_t
+
+The main structure, of type **afb_binding_t**, for describing the binding
+must be exported under the name **afbBindingExport**.
+
+This structure is defined as below.
+
+```C
+typedef struct afb_binding_v3 afb_binding_t;
+```
+
+Where:
+
+```C
+/**
+ * Description of the bindings of type version 3
+ */
+struct afb_binding_v3
+{
+ /** api name for the binding, can't be NULL */
+ const char *api;
+
+ /** textual specification of the binding, can be NULL */
+ const char *specification;
+
+ /** some info about the api, can be NULL */
+ const char *info;
+
+ /** array of descriptions of verbs terminated by a NULL name, can be NULL */
+ const struct afb_verb_v3 *verbs;
+
+ /** callback at load of the binding */
+ int (*preinit)(struct afb_api_x3 *api);
+
+ /** callback for starting the service */
+ int (*init)(struct afb_api_x3 *api);
+
+ /** callback for handling events */
+ void (*onevent)(struct afb_api_x3 *api, const char *event, struct json_object *object);
+
+ /** userdata for afb_api_x3 */
+ void *userdata;
+
+ /** space separated list of provided class(es) */
+ const char *provide_class;
+
+ /** space separated list of required class(es) */
+ const char *require_class;
+
+ /** space separated list of required API(es) */
+ const char *require_api;
+
+ /** avoids concurrent requests to verbs */
+ unsigned noconcurrency: 1;
+};
+```
+
+## The type afb_verb_t
+
+Each verb is described with a structure of type **afb_verb_t**
+defined below:
+
+```C
+typedef struct afb_verb_v3 afb_verb_t;
+```
+
+```C
+/**
+ * Description of one verb as provided for binding API version 3
+ */
+struct afb_verb_v3
+{
+ /** name of the verb, NULL only at end of the array */
+ const char *verb;
+
+ /** callback function implementing the verb */
+ void (*callback)(afb_req_t_x2 *req);
+
+ /** required authorization, can be NULL */
+ const struct afb_auth *auth;
+
+ /** some info about the verb, can be NULL */
+ const char *info;
+
+ /**< data for the verb callback */
+ void *vcbdata;
+
+ /** authorization and session requirements of the verb */
+ uint16_t session;
+
+ /** is the verb glob name */
+ uint16_t glob: 1;
+};
+```
+
+The **session** flags is one of the constant defined below:
+
+| Name | Description
+|:----------------------:|------------------------------------------------------
+| AFB_SESSION_NONE | no flag, synonym to 0
+| AFB_SESSION_LOA_0 | Requires the LOA to be 0 or more, synonym to 0 or AFB_SESSION_NONE
+| AFB_SESSION_LOA_1 | Requires the LOA to be 1 or more
+| AFB_SESSION_LOA_2 | Requires the LOA to be 2 or more
+| AFB_SESSION_LOA_3 | Requires the LOA to be 3 or more
+| AFB_SESSION_CHECK | Requires the token to be set and valid
+| AFB_SESSION_REFRESH | Implies a token refresh
+| AFB_SESSION_CLOSE | Implies closing the session after request processed
+
+The LOA (Level Of Assurance) is set, by binding api, using the function **afb_req_session_set_LOA**.
+
+The session can be closed, by binding api, using the function **afb_req_session_close**.
+
+## The types afb_auth_t and afb_auth_type_t
+
+The structure **afb_auth_t** is used within verb description to
+set security requirements.
+The interpretation of the structure depends on the value of the field **type**.
+
+```C
+typedef struct afb_auth afb_auth_t;
+
+/**
+ * Definition of an authorization entry
+ */
+struct afb_auth
+{
+ /** type of entry @see afb_auth_type */
+ enum afb_auth_type type;
+
+ union {
+ /** text when @ref type == @ref afb_auth_Permission */
+ const char *text;
+
+ /** level of assurancy when @ref type == @ref afb_auth_LOA */
+ unsigned loa;
+
+ /** first child when @ref type in { @ref afb_auth_Or, @ref afb_auth_And, @ref afb_auth_Not } */
+ const struct afb_auth *first;
+ };
+
+ /** second child when @ref type in { @ref afb_auth_Or, @ref afb_auth_And } */
+ const struct afb_auth *next;
+};
+
+```
+
+The possible values for **type** is defined here:
+
+```C
+typedef enum afb_auth_type afb_auth_type_t;
+
+/**
+ * Enumeration for authority (Session/Token/Assurance) definitions.
+ *
+ * @see afb_auth
+ */
+enum afb_auth_type
+{
+ /** never authorized, no data */
+ afb_auth_No = 0,
+
+ /** authorized if token valid, no data */
+ afb_auth_Token,
+
+ /** authorized if LOA greater than data 'loa' */
+ afb_auth_LOA,
+
+ /** authorized if permission 'text' is granted */
+ afb_auth_Permission,
+
+ /** authorized if 'first' or 'next' is authorized */
+ afb_auth_Or,
+
+ /** authorized if 'first' and 'next' are authorized */
+ afb_auth_And,
+
+ /** authorized if 'first' is not authorized */
+ afb_auth_Not,
+
+ /** always authorized, no data */
+ afb_auth_Yes
+};
+```
+
+Example:
+
+```C
+static const afb_auth_t myauth[] = {
+ { .type = afb_auth_Permission, .text = "urn:AGL:permission:me:public:set" },
+ { .type = afb_auth_Permission, .text = "urn:AGL:permission:me:public:get" },
+ { .type = afb_auth_Or, .first = &myauth[1], .next = &myauth[0] }
+};
+```
+
+
+## The type afb_req_subcall_flags_t
+
+This is an enumeration that defines bit's positions for setting behaviour
+of subcalls.
+
+| flag | value | description
+|----------------------------|-------|--------------
+| afb_req_subcall_catch_events | 1 | the calling API wants to receive the events from subscription
+| afb_req_subcall_pass_events | 2 | the original request will receive the events from subscription
+| afb_req_subcall_on_behalf | 4 | the calling API wants to use the credentials of the original request
+| afb_req_subcall_api_session | 8 | the calling API wants to use its session instead of the one of the original request
