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 On Windows platforms (excluding Cygwin), this function does usually not
18 recognize the @file{/dev/null} filename.
21 Portability problems fixed by the Gnulib module fchdir:
24 On Windows platforms (excluding Cygwin), this function fails to open a
25 read-only descriptor for directories.
28 Portability problems not fixed by Gnulib:
31 On Windows, this function returns a file handle in @code{O_TEXT} mode by
32 default; this means that it translates '\n' to CR/LF by default. Use the
33 @code{O_BINARY} flag if you need reliable binary I/O.
35 On platforms where @code{off_t} is a 32-bit type, @code{open} may not work
36 correctly with files larger than 2 GB. The fix is to use the
37 @code{AC_SYS_LARGEFILE} macro.
