tt_default_session(3)

NAME
     tt_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:

        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                The current default process identifier is out of date or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_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.
