Update.
1999-12-18 Ulrich Drepper <drepper@cygnus.com> * include/unistd.h: Declare __libc_open64, __libc_lseek64, __libc_pread, __libc_pread64, __libc_pwrite, and __libc_pwrite64. * io/Versions: Export __libc_open64 and __libc_lseek64. * posix/Versions: Export __libc_pread, __libc_pread64, __libc_pwrite, and __libc_pwrite64. * sysdeps/generic/open64.c: Define __libc_* variant for cancelation wrapper. * sysdeps/generic/pread.c: Likewise. * sysdeps/generic/pread64.c: Likewise. * sysdeps/generic/pwrite.c: Likewise. * sysdeps/generic/pwrite64.c: Likewise. * sysdeps/posix/open64.c: Likewise. * sysdeps/posix/pread.c: Likewise. * sysdeps/posix/pread64.c: Likewise. * sysdeps/posix/pwrite.c: Likewise. * sysdeps/posix/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/llseek.c: Likewise. * sysdeps/unix/sysv/linux/pread.c: Likewise. * sysdeps/unix/sysv/linux/pread64.c: Likewise. * sysdeps/unix/sysv/linux/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/i386/pread.c: Likewise. * sysdeps/unix/sysv/linux/i386/pread64.c: Likewise. * sysdeps/unix/sysv/linux/i386/pwrite.c: Likewise. * sysdeps/unix/sysv/linux/i386/pwrite64.c: Likewise. * sysdeps/posix/open64.c: Help gcc generating better code. * sysdeps/generic/libc-start.c (check_one_fd): Use __libc_open instead of __open.
