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 disposi-
tion 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 cor-
rect type for this operation.
