Revert(4)

NAME
Revert notice - discard any modifications to an entity

SYNOPSIS
[file] Revert(in type ID);

DESCRIPTION
The Revert notice asks that any pending, unsaved modifications 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.

ERRORS
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.

APPLICATION USAGE
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.
