5 POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/lstat.html}
9 Portability problems fixed by Gnulib:
12 On platforms where @code{off_t} is a 32-bit type, @code{lstat} may not
13 correctly report the size of files or block devices larger than 2 GB.
14 (Cf. @code{AC_SYS_LARGEFILE}.)
16 For symlinks, when the argument ends in a slash, some platforms don't
17 dereference the argument:
20 On some platforms, @code{lstat("file/",buf)} succeeds instead of
21 failing with @code{ENOTDIR}.
24 On Windows platforms (excluding Cygwin), symlinks are not supported, so
25 @code{lstat} does not exist.
28 Portability problems not fixed by Gnulib:
31 On Windows platforms (excluding Cygwin), @code{st_ino} is always 0.
33 Because of the definition of @code{struct stat}, it is not possible to
34 portably replace @code{stat} via an object-like macro. Therefore,
35 expressions such as @code{(islnk ? lstat : stat) (name, buf)} are not
36 portable, and should instead be written @code{islnk ? lstat (name,
37 buf) : stat (name, buf)}.
39 On some file systems, @code{st_size} contains bogus information for
40 symlinks; use the gnulib module areadlink-with-size for a better way
41 to get symlink contents.
