From 3a8db22f07e2ab5373d4a366672a7a7b158ada96 Mon Sep 17 00:00:00 2001 From: Andreas Jaeger Date: Wed, 24 Oct 2012 08:57:47 +0200 Subject: Always define off_t, mode_t, pid_t * io/fcntl.h: Always define mode_t, off_t, pid_t and use these types for creat, creat64, lockf, posix_fadvise, posix_fallocate. [__USE_LARGEFILE64 && !__off64_t_defined]: Define off64_t.
