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 identifier 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 service 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The current default process identifier is out of date or invalid.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.
