Function: vc-resynch-buffer

vc-resynch-buffer is a byte-compiled function defined in vc-dispatcher.el.gz.

Signature

(vc-resynch-buffer FILE &optional KEEP NOQUERY RESET-VC-INFO)

Documentation

If FILE is currently visited, resynch its buffer.

If NOQUERY is unless-modified then silently skip reverting or unvisiting if the buffer is modified. Any other non-nil value inhibits getting confirmation before reverting. NOQUERY should be a non-nil value other than unless-modified only if it is known that the only difference between the buffer and the file is due to modifications by the dispatcher client code, rather than user editing.
