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