NAME
  tt_pattern_class_add - add a value to the class information for a pattern

SYNOPSIS
  #include <tt_c.h>
  Tt_status tt_pattern_class_add(Tt_pattern p,
				 Tt_class c);

DESCRIPTION
  The tt_pattern_class_add function adds a value to the class information for
  the specified pattern.

  If the class is TT_REQUEST, the sending process expects a reply to the
  message.

  If the class is TT_NOTICE, the sending process does not expect a reply to
  the message.

  The p argument is a unique handle for a message pattern. This handle is
  returned after tt_pattern_create(3) is called. The c argument indicates
  whether the receiving process is to take action after the message is
  received. The following values are defined:

  TT_NOTICE
      A notice of an event.  The sender does not want feedback on this
      message.

  TT_REQUEST
      A request for some action to be taken. The sender must be notified of
      progress, success or failure, and must receive any return values.

RETURN VALUE
  Upon successful completion, the tt_pattern_class_add 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.
