The ttdt_file_event() function uses the ToolTalk service to announce an event about a file. This function creates and, optionally, sends a ToolTalk notice that announces an event pertaining to a specified file. This file is indicated in the path name that was passed to the ttdt_file_join() function when the patterns were created.

• Table A-3 describes the effect of the value of the event parameter on the announcement made.

Table A-3 Effect of event Parameter

Event Announced	Announcement
TTDT_MODIFIED	Registers in the scope passed to the ttdt_file_join() function to announce the event to interested tools that handle Get_Modified, Save, and Revert requests.
TTDT_SAVED, TTDT_REVERTED	Unregisters handler patterns for Get_Modified, Save, and Revert requests.  If the send parameter is set, this function sends a Saved or Reverted notice, respectively, in the scope.

• If the send parameter is set, this function sends the Modified notice in the scope.

• If the context parameter is a value other than zero, messages created by this routine inherit all contexts whose slot name begins with ENV_.
