This function is missing on some platforms:
|
|
MSVC 14.

@item
|
|
On platforms where @code{off_t} is a 32-bit type, this function may not
|
|
work correctly on huge directories 2 GiB and larger. Also, on platforms
|
|
where @code{ino_t} is a 32-bit type, this function may report inode numbers
|
|
incorrectly. This can occur with file systems such as XFS (typically on
|
|
large disks) and NFS@. @xref{Large File Support}.

Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
Although POSIX places no restrictions on @code{d_ino} values, some
|
|
older systems are rumored to return @code{d_ino} values equal to zero
|
|
for directory entries that do not really exist. Although Gnulib
|
|
formerly attempted to cater to these older systems, this caused
|
|
misbehavior on standard systems and so Gnulib does not attempt to
|
|
cater to them any more. If you know of any problems caused by this,
|
|
please send a bug report.
