@node fopen @section @code{fopen} @findex fopen POSIX specification: @url{http://www.opengroup.org/susv3xsh/fopen.html} Gnulib module: fopen Portability problems fixed by Gnulib: @itemize @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 On Windows platforms (excluding Cygwin), this function does usually not recognize the @file{/dev/null} filename. @end itemize Portability problems not fixed by Gnulib: @itemize @item On Windows platforms (excluding Cygwin), this function does not set @code{errno} upon failure. @item On Windows, this function returns a file stream in ``text'' mode by default; this means that it translates @code{'\n'} to CR/LF by default. Use the @code{"b"} flag if you need reliable binary I/O. @item On Windows platforms (excluding Cygwin), this function fails to open directories for reading. Such streams have implementation-defined semantics on other platforms. To avoid directory streams with a consistent error message, use @code{fstat} after @code{open} and @code{fdopen}, rather than @code{fopen} and @code{fileno}. @end itemize
