nate 1745c06559 Date: Wed, 26 Oct 1994 15:44:49 -0600 ... From: Chris Torek <torek@bsdi.com> Here is a semi-official patch (apply to /usr/src/lib/libc/stdio/fseek.c, rebuild libc, install). The current code fails when the seek: - is optimized, and - is to just past the end of the block currently in the buffer, and - is followed by another seek with no intervening read operation, and - the destination of subsequent seek is within the block left in the buffer (seeking to the beginning of a block does not force a read, so the buffer still contains the previous block) so it is indeed rather obscure. I may have a different `final' fix, as this one `loses' the buffer contents on a seek that goes just past the end of the current block. [Footnote: seeks are optimized only on read-only opens of regular files that are buffered by the file's optimal I/O size. This is what you get with fopen(path, "r") and no call to setvbuf().] Obtained from: [ BSDI mailing list ]		1994-11-05 18:49:34 +00:00
