9 Portability problems fixed by Gnulib:
12 This function is missing on some platforms:
13 glibc 2.3.6, MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, AIX
14 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.5.x, mingw, Interix 3.5, BeOS.
15 But the replacement function is not safe to be used in libraries and is not multithread-safe.
17 This function does not fail when the file name argument ends in a slash
18 and (without the slash) names a nonexistent file or a file that is not a
19 directory, on some platforms:
23 Portability problems not fixed by Gnulib:
26 On platforms where @code{off_t} is a 32-bit type, @code{open} may not work
27 correctly with files larger than 2 GB. The fix is to use the
28 @code{AC_SYS_LARGEFILE} macro.
