(OPENAT_CWD_RESTORE__ALLOW_FAILURE): Likewise.
(fd_to_subdirp): Remove openat_cwd_restore_allow_failure arg; its
value is now signified by whether cwd_errno is null.
(fd_to_subdirp, remove_dir, rm_1); Change cwd failure indicator from
pointer-to-bool to pointer-to-errno-value. All callers changed.
(rm_1): Don't bother setting a local cwd failure flag and then
ORing it into the caller's. Just set the caller's.
(rm): Use cwd failure errno value to print a slightly-better
diagnostic.
"gettext.h"; either no longer needed or are guaranteed by openat.h.
(_): Remove; no longer needed.
(openat): Renamed from rpl_openat; no need for rpl_openat
since openat.h renames openat for us.
Replace most of the body with a call to openat_permissive,
to avoid duplicate code.
Port to (probably hypothetical) environments were mode_t is
wider than int.
(openat_permissive): Require mode arg, so that we can check
types better. Put it just after flags. Change cwd failure
indicator from pointer-to-bool to pointer-to-errno-value.
All callers changed.
Invoke openat_save_fail and/or openat_restore_fail if
cwd_errno is null, so that openat can call us.
(openat_permissive, fdopendir, fstatat, unlinkat):
Simplify errno handling to avoid some duplicate code,
as it's OK to set errno on success.
__OPENAT_PREFIX only, not also on AT_FDCWD.
(openat_ro): Remove. Caller changed to use openat_permissive.
(openat_permissive): Now a macro, if not a function.
(openat_restore_fail, openat_save_fail): Now always functions,
since mkdirat needs them even if __OPENAT_PREFIX is defined.
add new option: --printf=FMT
(isodigit, octtobin, hextobin): Define.
(PRINTF_OPTION): Define.
(interpret_backslash_escapes, trailing_delim): New globals.
(usage): Document them. Alphabetize on long option names.
(print_esc_char): New function.
(print_it): Rewrite, in order to handle backslash escapes.
(main): Handle new option. Set globals for --format, too.
(check_ordering_compatibility, main): Use it.
(main): Check for -c and -o.
Don't bother with a usage message for
"sort -c a b", for consistency with other error diagnostics.
