tt_pattern_register(3)
CDE


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_create3 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 ttsession1 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  The specified process identifier is out of date or invalid.
