7 Gnulib module: open, fchdir
9 Portability problems fixed by the Gnulib module open:
12 On platforms where @code{off_t} is a 32-bit type, @code{open} may not work
13 correctly with files larger than 2 GB. (Cf. @code{AC_SYS_LARGEFILE}.)
15 This function does not fail when the file name argument ends in a slash
16 and (without the slash) names a nonexistent file or a file that is not a
17 directory, on some platforms:
18 FreeBSD 7.2, AIX 7.1, HP-UX 11.00, Solaris 9, Irix 5.3.
20 This function does not support the @code{O_NONBLOCK} flag when it is defined
21 by the gnulib module @code{nonblocking} on some platforms:
24 On Windows platforms (excluding Cygwin), this function does usually not
25 recognize the @file{/dev/null} filename.
28 Portability problems fixed by the Gnulib module fchdir:
31 On Windows platforms (excluding Cygwin), this function fails to open a
32 read-only descriptor for directories.
35 Portability problems not fixed by Gnulib:
38 On Windows, this function returns a file handle in @code{O_TEXT} mode by
39 default; this means that it translates @code{'\n'} to CR/LF by default. Use the
40 @code{O_BINARY} flag if you need reliable binary I/O.
