std.stdio File I/O is not fully complete

[dymk]

This program:

import std.stdio;

void main() {
    auto f = File("testfile.tmp", "wb+");

    ubyte[4] buffer = [1, 2, 3, 4];
    f.rawWrite(buffer);
    f.seek(0);
    f.rawRead(buffer);
    writeln(buffer);
}

fails to build, emitting the error:

$ ldmd2 ldcio.d
G:/Programs/LDC/include/d\std\stdio.d(665): Error: undefined identifier '_fileno', did you mean 'function fileno'?
G:/Programs/LDC/include/d\std\stdio.d(666): Error: undefined identifier '_setmode'
G:/Programs/LDC/include/d\std\stdio.d(666): Error: undefined identifier _O_BINARY
G:/Programs/LDC/include/d\std\stdio.d(667): Error: undefined identifier '_setmode'
ldcio.d(7): Error: template instance std.stdio.File.rawWrite!(ubyte) error instantiating

The build succeeds and runs correctly using DMD:

$ dmd ldcio.d && ldcio.exe
[1, 2, 3, 4]

I ran into the problem with DMD when building for 64 bit (the bugreport for it is (located here)[http://d.puremagic.com/issues/show_bug.cgi?id=10227], and my hackey fix was to replace these lines (117-138) of stdio.d:

else version (MICROSOFT_STDIO)
{
    extern (C)
    {
        /* **
         * Microsoft under-the-hood C I/O functions
         */
        int _fputc_nolock(int, _iobuf*);
        int _fputwc_nolock(int, _iobuf*);
        int _fgetc_nolock(_iobuf*);
        int _fgetwc_nolock(_iobuf*);
        void _lock_file(FILE*);
        void _unlock_file(FILE*);
    }
    alias _fputc_nolock FPUTC;
    alias _fputwc_nolock FPUTWC;
    alias _fgetc_nolock FGETC;
    alias _fgetwc_nolock FGETWC;

    alias _lock_file FLOCK;
    alias _unlock_file FUNLOCK;
}

With:

else version (MICROSOFT_STDIO)
{
    extern (C)
    {
        /* **
         * Microsoft under-the-hood C I/O functions
         */
        int _fputc_nolock(int, _iobuf*);
        int _fputwc_nolock(int, _iobuf*);
        int _fgetc_nolock(_iobuf*);
        int _fgetwc_nolock(_iobuf*);
        void _lock_file(FILE*);
        void _unlock_file(FILE*);
        int _setmode(int, int);
        int _fileno(FILE*);
    }
    alias _fputc_nolock FPUTC;
    alias _fputwc_nolock FPUTWC;
    alias _fgetc_nolock FGETC;
    alias _fgetwc_nolock FGETWC;

    alias _lock_file FLOCK;
    alias _unlock_file FUNLOCK;

    enum _O_BINARY = 0x8000;

}

With this "fix" (I'm not sure how stable it is), both DMD and LDC compile and run as expected.

Created PR dlang/phobos#1538 for phobos.

[redstar]

Set to upstream pending as the mentioned PR is already merged.

[dnadlinger]

Should have landed in LDC by now.
