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The current default process identifier is out of date or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.
