Subject: mmap with __USE_FILE_OFFSET64
Date: Mon, 15 Nov 1999 08:36:00 -0000 [thread overview]
Message-ID: <u8yabzhgbe.fsf@gromit.rhein-neckar.de> (raw)
Looking at the usage of __USE_FILE_OFFSET64, I noticed a problem with
the mmap system call.
We should use __off64_t instead of just off_t and also use __REDIRECT
--- as we do in all other usages of __USE_FILE_OFFSET64.
I'm appending a patch for inclusion in glibc 2.2 and 2.1.3.

* misc/sys/mman.h: Use __REDIRECT for mmap, correct prototype to
use __off64_t.
