| Gnulib module: fstatat |
| |
| Portability problems fixed by Gnulib: |
| @itemize |
| @item |
| This function is missing on some platforms: |
| glibc 2.3.6, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, |
| AIX 5.1, HP-UX 11, IRIX 6.5, Cygwin 1.5.x, mingw, MSVC 14. |
| But the replacement function is not safe to be used in libraries and is not multithread-safe. |
| @item |
| On platforms where @code{off_t} is a 32-bit type, @code{fstatat} may |
| not correctly report the size of files or block devices larger than 2 |
| GB. (Cf. @code{AC_SYS_LARGEFILE}.) |
| @item |
| On some platforms, @code{fstatat(fd,"file/",buf,flag)} succeeds instead of |
| failing with @code{ENOTDIR}. |
| Solaris 9. |
| @item |
| For symlinks, when the argument ends in a slash, some platforms don't |
| dereference the argument: |
| Solaris 9. |
| @item |
| On Solaris 11.4, when this function yields a timestamp with a |
| nonpositive @code{tv_sec} value, @code{tv_nsec} might be in the range |
| @minus{}1000000000..@minus{}1, representing a negative nanoseconds |
| offset from @code{tv_sec}. |
