@brief Calls the registered handler of an endpoint session for processing incoming data and generating the response

@note

• An endpoint must be bound to a valid protocomm instance, created using protocomm_new().
• Resulting output buffer must be deallocated by the caller.

@param[in] pc Pointer to the protocomm instance @param[in] ep_name Endpoint identifier(name) string @param[in] session_id Unique ID for a communication session @param[in] inbuf Input buffer contains input request data which is to be processed by the registered handler @param[in] inlen Length of the input buffer @param[out] outbuf Pointer to internally allocated output buffer, where the resulting response data output from the registered handler is to be stored @param[out] outlen Buffer length of the allocated output buffer

@return

• ESP_OK : Request handled successfully
• ESP_FAIL : Internal error in execution of registered handler
• ESP_ERR_NO_MEM : Error allocating internal resource
• ESP_ERR_NOT_FOUND : Endpoint with specified name doesn’t exist
• ESP_ERR_INVALID_ARG : Null instance/name arguments
