+/**
+ * \par Description:
+ * Creates a client session string based on pid and time of creation of client process
+ *
+ * \par Purpose:
+ * This function can be used to create session string identifier used in cynara_check()
+ * and cynara_async_create_request() functions defined in  client libraries.
+ *
+ * \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_session param in cynara_check() or
+ * cynara_async_create_request() function. String is released with free() function.
+ *
+ * \par Method of function operation:
+ * The function generates client session based on the pid and start time of the client process.
+ * Time is acquired from /proc/PID directory.
+ *
+ * \par Sync (or) Async:
+ * This is a synchronous API.
+ *
+ * \par Thread safety:
+ * This function is thread-safe.
+ *
+ * \par Important notes:
+ * Memory for returned string is obtained with malloc(), and should be freed with free().
+ *
+ * \param[in] client_pid client application process identifier (PID).
+ *
+ * \return session string on success
+ * \return NULL on error
