tt_thread_session(3) ToolTalk Functions tt_thread_session(3) NAME tt_thread_session - retrieve the default session identifier for the currently active thread SYNOPSIS #include <Tt/tt_c.h> char *tt_thread_session ( void ); DESCRIPTION The tt_thread_session() function retrieves the default session identi- fier for the currently active thread. If there is no default session set for the currently-active thread, then the process default session identifier is returned. RETURN VALUE Upon successful completion, the tt_thread_session() function returns the pointer to the unique identifier for the active thread's current default session. If the pointer is NULL, no default session is set. The application can use tt_ptr_error(3) to extract one of the following Tt_status values from the returned pointer: TT_OK The operation completed successfully. TT_ERR_NOMP The ttsession(1) process is not running and the ToolTalk ser- vice cannot restart it. TT_ERR_PROCID The current default process identifier is out of date or invalid. APPLICATION USAGE A session can have more than one session identifier. This means that the application cannot compare the result of tt_thread_session() with the result of tt_message_session(3) to verify that the message was sent in the default session. The application should use tt_free(3) to free any data stored in the address returned by the ToolTalk API.
