ttdt_Revert

Tt_status    ttdt_Revert(	Tt_message    	  context,
  						const char *    pathname,
  						Tt_scope       the_scope, 
							XtAppContext	   app2run,
   					int             ms_timeout
);

The ttdt_Revert() function requests a ToolTalk client to revert a file. It sends a Revert request in the_scope and waits for a reply. The Revert request asks the handling ToolTalk client to discard any changes pending on pathname.

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

• If the value of the the_scope parameter is zero (that is, TT_SCOPE_NONE), the file scope is set to the default (TT_BOTH); however, if, for example, the ToolTalk database server rpc.ttdbserver is not installed on the file server that owns pathname, the file scope is set to TT_FILE_IN_SESSION.

• The app2run and ms_timeout parameters are passed to the tttk_block_while() function to block on the reply to the Revert request sent by this function.

If the request receives an affirmative reply within the indicated timeout, the ttdt_Revert() function returns TT_OK; otherwise, it returns either the tt_message_status of the failure reply, or one of the errors listed in Table A-13.
