RETURN VALUE Upon successful completion, the tt_default_session() function returns the pointer to the unique identifier for the 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: The operation completed successfully. The ttsession(1) process is not running and the ToolTalk service cannot restart it. The current default process identifier is out of date or invalid.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_default_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.
