tt_pattern_register(3) — Subroutines
CDE
NAME
tt_pattern_register − register a pattern with the ToolTalk service
SYNOPSIS
#include <tt_c.h> Tt_status tt_pattern_register(Tt_pattern p);
DESCRIPTION
The tt_pattern_register function registers a pattern with the ToolTalk service.
When the process is registered, it will start receiving messages that match the specified pattern. Once a pattern is registered, no further changes can be made in the pattern.
When the process joins a session or file, the ToolTalk service updates the file and session field of its registered patterns.
The p argument is a unique handle for a message pattern. This handle is returned after tt_pattern_create(3) is called.
RETURN VALUE
Upon successful completion, the tt_pattern_register 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.
TT_ERR_PROCID
The specified process identifier is out of date or invalid.
