tt_pattern_register(3) C LIBRARY FUNCTIONS tt_pattern_register(3)
NAME
tt_pattern_register - register a pattern with the ToolTalk
service
SYNOPSIS
#include <Tt/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 mes-
sages 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 ser-
vice 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() func-
tion returns the status of the operation as one of the fol-
lowing 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The specified process identifier is out of date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.
