Gnulib module: freopen

Portability problems fixed by Gnulib:
|
|
@itemize

|
@item
|
|
On platforms where @code{off_t} is a 32-bit type, @code{freopen} may not work
|
|
correctly with files larger than 2 GB. (Cf. @code{AC_SYS_LARGEFILE}.)
|
|
@item
|
|
On Windows platforms (excluding Cygwin), this function does usually not
|
|
recognize the @file{/dev/null} filename.

Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
On Windows platforms (excluding Cygwin), this function does not set @code{errno}
|
|
upon failure.
|
|
@item
|
|
This function does not support a @code{NULL} file name argument on some
|
|
platforms:
|
|
OpenBSD 4.9, AIX 7.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 10, mingw, MSVC 9.
|
|
@item
|
|
This function does not fail when the file name argument ends in a slash
|
|
and (without the slash) names a nonexistent file or a file that is not a
|
|
directory, on some platforms:
|
|
HP-UX 11.00, Solaris 9, Irix 5.3.
|
|
@item
|
|
Applications should not assume that @code{fileno(f)} will be the same
|
|
before and after a call to @code{freopen(name,mode,f)}. However, the
|
|
module freopen-safer can at least protect @code{stdin}, @code{stdout},
|
|
and @code{stderr}.
