Subject: truncate head of file?
Date: Tue, 19 Aug 2014 22:45:16 -0700 [thread overview]
Message-ID: <53F435EC.4030601@symas.com> (raw)
Was thinking it would be very handy to have a truncate() variant that deletes
pages from the head of a file. This could be leveraged to make logfiles easier
to maintain, as an example. Anyone else interested, think this would be nice
to have?
(Note - not the same as just punching holes in the beginning of the file - we
want the beginning of the file to advance as well, past the deleted pages.)
