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 pro- cess 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 mes- sage 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. SEE ALSO tt_c(5), tt_pattern_create(3).
