NAME
     tt_pattern_disposition_add - add a value to the disposition field for a
     pattern

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_status tt_pattern_disposition_add(Tt_pattern p,
                                          Tt_disposition r);

DESCRIPTION
     The tt_pattern_disposition_add() function adds a value to the disposition
     field for the specified pattern.

     The p argument is a unique handle for a message pattern.  This handle is
     returned after tt_pattern_create(3) is called.

     The r argument indicates whether an instance of the receiver is to be
     started to receive the message immediately, or whether the message is to
     be queued until the receiving process is started at a later time or
     discarded if the receiver is not started.  The following values are
     defined:

        TT_DISCARD
                There is no receiver for this message.  The message will be
                returned to the sender with the Tt_status field containing
                TT_FAILED.

        TT_QUEUE
                Queue the message until a process of the proper ptype receives
                the message.

        TT_START
                Attempt to start a process of the proper ptype if none is
                running.

        TT_QUEUE+TT_START
                Queue the message and attempt to start a process of the proper
                ptype if none is running.

RETURN VALUE
     Upon successful completion, the tt_pattern_disposition_add() function
     returns the status of the operation as one of the following Tt_status
     values:

        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_POINTER
                The pointer passed does not point to an object of the correct
                type for this operation.
