(__fdopen): Use INTUSE. * sysdeps/mach/hurd/tmpfile64.c: New file, empty placeholder. * stdio-common/tmpfile64.c: File removed. * sysdeps/generic/tmpfile64.c: New file. * sysdeps/generic/tmpfile.c (GEN_THIS): New macro, define to __GT_FILE if not already defined. (tmpfile): Use it in place of __GT_FILE. * include/unistd.h: Declare __chown_internal. * sysdeps/mach/hurd/sendfile64.c (sendfile64): Do real work here. * sysdeps/mach/hurd/sendfile.c (sendfile): Call that. 2002-06-09 Roland McGrath Update to new Hurd RPC interfaces supporting 64-bit file sizes. * sysdeps/mach/hurd/configure.in: Check for with value of HURD_INTERFACE_VERSION >= 20020609. * sysdeps/mach/hurd/configure: Regenerated. * shlib-versions (.*-.*-gnu-gnu.*): Set libhurduser=0.3. * sysdeps/mach/hurd/xstatconv.c (xstat64_conv): Rewritten to convert a struct stat64 into a struct stat and return 0 or -1 with errno set to EOVERFLOW. * sysdeps/mach/hurd/statfsconv.c (statfs64_conv): Likewise for struct statfs64 to struct statfs. * sysdeps/mach/hurd/xstat.c (__xstat): Use converter and call ... * sysdeps/mach/hurd/xstat64.c (__xstat64): ... this, real work here. * sysdeps/mach/hurd/fxstat.c (__fxstat): Likewise. * sysdeps/mach/hurd/fxstat64.c (__fxstat64): Likewise. * sysdeps/mach/hurd/lxstat.c (__lxstat): Likewise. * sysdeps/mach/hurd/lxstat64.c (__lxstat64): Likewise. * sysdeps/mach/hurd/statfs.c (__statfs): Likewise. * sysdeps/mach/hurd/statfs64.c (__statfs64): Likewise. * sysdeps/mach/hurd/fstatfs.c (__fstatfs): Likewise. * sysdeps/mach/hurd/fstatfs64.c (__fstatfs64): Likewise. * sysdeps/mach/hurd/pwrite64.c (__libc_pwrite64): Do real work here. * sysdeps/mach/hurd/pwrite.c (__libc_pwrite): Call that. * sysdeps/mach/hurd/pread64.c (__libc_pread64): Do real work here. * sysdeps/mach/hurd/pread.c (__libc_pread): Call that. * sysdeps/mach/hurd/lseek64.c (__libc_lseek64): Do real work here. * sysdeps/mach/hurd/lseek.c (__libc_lseek): Call that. * sysdeps/mach/hurd/readdir64.c (__readdir64): Do real work here. * sysdeps/mach/hurd/readdir.c (__readdir): Call that. * sysdeps/mach/hurd/readdir64_r.c (__readdir64_r): Do real work here. * sysdeps/mach/hurd/readdir_r.c (__readdir64_r): Call that. * hurd/lookup-retry.c (__hurd_file_name_lookup_retry): Use struct stat64 for io_stat argument. * sysdeps/mach/hurd/readlink.c (__readlink): Likewise. * hurd/fopenport.c (seekio): Remove EOVERFLOW check, pass POS directly to io_seek. * hurd/fd-read.c (_hurd_fd_read): Use loff_t for OFFSET argument. * hurd/fd-write.c (_hurd_fd_write): Likewise. * hurd/hurd/fd.h: Update decls. * sysdeps/mach/hurd/getcwd.c (_hurd_canonicalize_directory_name_internal): Use ino64_t and struct dirent64. * sysdeps/mach/hurd/dl-sysdep.c (open_file): Use struct stat64. (__xstat): Renamed to __xstat64, use struct stat64 for argument. (__fxstat): Renamed to __fxstat64, use struct stat64 for argument. (__lseek): Renamed to __libc_lseek64, use off64_t for argument. 2002-06-08 Roland McGrath * sysdeps/mach/hurd/dirstream.h (struct __dirstream): Use size_t instead of unsigned long int for __allocation and __size members. 2002-05-19 Ulrich Drepper --- sysdeps/mach/hurd/readdir.c | 111 ++++++++++++++------------------------------ 1 file changed, 36 insertions(+), 75 deletions(-) (limited to 'sysdeps/mach/hurd/readdir.c') diff --git a/sysdeps/mach/hurd/readdir.c b/sysdeps/mach/hurd/readdir.c index 6e986f3ebb..4bf19564d7 100644 --- a/sysdeps/mach/hurd/readdir.c +++ b/sysdeps/mach/hurd/readdir.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1993, 1994, 1995, 1996, 1997 Free Software Foundation, Inc. +/* Copyright (C) 1993,94,95,96,97,2002 Free Software Foundation, Inc.
