tt_default_session(3)

tt_default_session(3)  C LIBRARY FUNCTIONS  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()  func-
     tion  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		The current default process identifier is out  of
		date or	invalid.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.

SEE ALSO
     Tttt_c(5),	tt_ptr_error(3), tt_free(3).
