NAMEtt_default_session - retrieve the current default session identifier
SYNOPSIS
#include <Tt/tt_c.h>
char *tt_default_session(void);
DESCRIPTION
The tt_default_session() function retrieves the current default session
identifier.
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The current default process identifier is out of date or invalid.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.
