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:

        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                The specified process identifier is out of date or invalid.
