Portability problems fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
On platforms where @code{off_t} is a 32-bit type, @code{lstat} may not
|
|
correctly report the size of files or block devices 2 GiB and larger.
|
|
@xref{Large File Support}.
|
|
@item
|
|
On Linux/x86 and Linux/x86_64, applications compiled in 32-bit mode cannot
|
|
access files that happen to have a 64-bit inode number. This can occur with
|
|
file systems such as XFS (typically on large disks) and NFS.

For symlinks, when the argument ends in a slash, some platforms don't
|
|
dereference the argument:
|
|
Solaris 9.
|
|
@item
|
|
On some platforms, @code{lstat("file/",buf)} succeeds instead of
|
|
failing with @code{ENOTDIR}.
|
|
macOS 14, Solaris 9.
|
|
@item
|
|
On macOS 12.6, when this function yields a timestamp with a
|
|
nonpositive @code{tv_sec} value, @code{tv_nsec} might be in the range
|
|
@minus{}999999999..@minus{}1, representing a negative nanoseconds
|
|
offset from @code{tv_sec}. Solaris 11.4 is similar, except that
|
|
@code{tv_sec} might also be @minus{}1000000000.
|
|
@item
|
|
On Windows platforms (excluding Cygwin), symlinks are not supported, so
|
|
@code{lstat} does not exist.
