- (file-move ORIGFILE NEWFILE #!optional CLOBBER BLOCKSIZE) procedure
Moves ORIGFILE (a string denoting some filename) to NEWFILE, with the same semantics as file-copy, above. file-move is safe across filesystems and devices (unlike rename-file). It is possible for an error to be signalled despite partial success if NEWFILE could be created and fully written but removing ORIGFILE fails.
