Revert notice - discard any modifications to an entity
[file] Revert(in type ID);
The Revert notice asks that any pending, unsaved modifica-
tions to a persistent entity (such as a file) be discarded.
The ID argument is the identity of the entity to revert.
When its type is File, then the ID argument is unset (in
other words, has a value of (char *)0), and it refers to the
file or directory named in the message's file attribute.
The ToolTalk service may return one of the following errors
in processing the Revert notice:
The entity had no pending, unsaved modifications.
The file to save/revert does not exist.
The ttdt_file_join(3), function can be used to register for,
and help process, the Revert request.
The Revert request can be sent with ttdt_file_request(3).
Also, ttdt_Revert(3), can send the relevant message and
block on the reply.
ttdt_Revert(3), ttdt_file_join(3), ttdt_file_request(3);
