librarie are separated and isolated.

The option WITH_CYNARA_COMPAT activates it or not.

+/**
+ * \par Description:
+ * Creates a client identification string with given method. Client is a current process.
+ *
+ * \par Purpose:
+ * Client identification string is required for cynara_check() and cynara_async_create_request()
+ * functions.
+ *
+ * \par Typical use case:
+ * The function is called before the call of cynara_check() or cynara_async_create_request()
+ * function. Returned string is used as client parameter in cynara_check() or
+ * cynara_async_create_request() function. String is released with free() function when it is no
+ * longer needed.
+ *
+ * \par Method of function operation:
+ * The function generates client string using current process context.
+ *
+ * \par Sync (or) Async:
+ * This is a synchronous API.
+ *
+ * \par Thread safety:
+ * This function is NOT thread-safe. If functions from described API are called by multithreaded
+ * application from different threads, they must be put into mutex protected critical section.
+ *
+ * \par Important notes:
+ * Memory for returned client string is obtained with malloc(), and should be freed with free().
+ * Allocated string is returned only, when function succeeds.
+ * If method is CLIENT_METHOD_DEFAULT then it will be chosen based on Cynara configuration file.
+ *
+ * \param[in] method Method of client identifier creation
+ * \param[out] client Placeholder for allocated string containing client id
+ *
+ * \return CYNARA_API_SUCCESS on success
+ * \return CYNARA_API_INVALID_PARAM when client is NULL
+ * \return CYNARA_API_METHOD_NOT_SUPPORTED when requested method is not supported
+ * \return CYNARA_API_CONFIGURATION_ERROR if the configuration file can not be opened or
+ *                                        there are errors in configuration file
+ * \return CYNARA_API_OUT_OF_MEMORY when there was error allocating memory
