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 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:

    The operation completed successfully.
    The ttsession(1) process is not running and the ToolTalk service cannot restart it.
    The pointer passed does not point to an object of the correct type for this operation.
    The specified process identifier is out of date or invalid.
