     tt_procid_session - identify the session in which the  indi-
     cated procid was opened

SYNOPSIS
     #include <Tt/tt_c.h>
     char *tt_procid_session ( char *procid );

DESCRIPTION
     The tt_procid_session() function retrieves  the  session  in
     which the given procid was opened.

     The procid argument is a pointer to  the  unique  identifier
     for the ToolTalk process in which the caller is interested.

RETURN VALUE
     Upon successful completion, the tt_procid_session() function
     returns  the   pointer  to  a character string that uniquely
     identifies the session which was the default session at  the
     time  the  procid  argument  was returned by a tt_open(3) or
     ttdt_open(3) call. 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             The current default process  identifier  is  out  of
             date or invalid.

     stored in the address returned by the ToolTalk API.
