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_open3 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 values: The
  operation completed successfully.
  The ttsession1 process is not running and the ToolTalk service cannot
  restart it.
  The current default process identifier is out of date or invalid.
  The specified ToolTalk session is out of date or invalid.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_open3

  The tt_open3 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_open3
       tt_default_session3

  The application can then store the information by indexing it by the procid
  returned by the tt_open3 call.
