NAME
     tt_pnotice_create - create a procedure notice

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_message tt_pnotice_create(Tt_scope scope,
                                  const char *op);

DESCRIPTION
     The tt_pnotice_create() function  creates  a  message.   The
     created message contains the following:

           Tt_address = TT_PROCEDURE
           Tt_class = TT_NOTICE

     The application can use the returned handle to add arguments
     and other attributes, and to send the message.

     The scope argument determines which processes  are  eligible
     to receive the message.  The following values are defined:

        TT_SESSION
                All processes joined to the indicated session are
                eligible.

        TT_FILE
                All processes joined to the  indicated  file  are
                eligible.

        TT_BOTH
                All processes joined to either indicated file  or
                the indicated session are eligible.

        TT_FILE_IN_SESSION
                All processes joined to both the  indicated  file
                and the indicated session are eligible.

     The op argument is the operation  to  be  performed  by  the
     receiving process.

RETURN VALUE
     Upon successful completion, the tt_pnotice_create() function
     returns the unique handle that identifies this message.  The
     application can use tt_ptr_error(3) to extract  one  of  the
     following Tt_status values from the returned handle:

        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                The specified process identifier is out  of  date
                or invalid.

APPLICATION USAGE
     The application should  use  tt_free(3)  to  free  any  data
     stored in the address returned by the ToolTalk API.

     If the ToolTalk service is unable to create a  message  when
     requested,  tt_pnotice_create()  returns  an invalid handle.
     When the  application  attempts  to  use  this  handle  with
     another  ToolTalk function, the ToolTalk service will return
     TT_ERR_POINTER.

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