NAME

       tt_default_session_set -- set the current default session identifier

SYNOPSIS

       #include <Tt/tt_c.h>
       Tt_status tt_default_session_set(
       const char *sessid);

DESCRIPTION

       The tt_default_session_set function sets the current default session identifier.

       The  ToolTalk  service  uses the initial user session as the default session and supports one session per procid.  The application can make
       this call before it calls tt_open(3) to specify the session to which it wants to connect.

       The sessid argument is a pointer to the unique identifier for the session in which the procid is interested.

RETURN VALUE

       Upon successful completion, the tt_default_session_set function returns the status of the operation as one of the following Tt_status  val-
       ues:

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		 The current default process identifier is out of date or invalid.

       TT_ERR_SESSION
		 The specified ToolTalk session is out of date or invalid.

APPLICATION USAGE

       To change to another opened session, the application must use the tt_default_procid_set function.

       To  join  other	sessions,  the	procid	must  first  set the new session as the default session, and then initialize and register with the
       ToolTalk service.  The calls required must be in the following order:

       tt_default_session_set
       tt_open

       The tt_open(3) may create another ToolTalk procid, the connection to which is identified by a procid.  Only one ToolTalk session per procid
       is allowed.  (However, multiple procids are allowed in a client.)  There are no API calls to determine to which session a particular procid
       is connected.  If it is important for the application to know the session to which it is connected, it must make the following calls in the
       indicated order:

       tt_open
       tt_default_session

       The application can then store the information by indexing it by the procid returned by the tt_open(3) call.
