Hmm, confusing stuff.
On http://msdn.microsoft.com/en-us/library/ms860492.aspx you'll find
that _fileno returns an int value. I believe that _fileno and fileno are
the same, but I may be mistaken.
MSDN also mentions that _fileno is ISO C++ conformant, and fileno is
deprecated.
Our src/mingw/include/stdio.h says :
#ifndef __COREDLL__
_CRTIMP int __cdecl __MINGW_NOTHROW fgetchar (void);
_CRTIMP int __cdecl __MINGW_NOTHROW fputchar (int);
_CRTIMP int __cdecl __MINGW_NOTHROW fileno (FILE*);
#else
/* We know the Microsoft defines _fileno as returning
a void* (HANDLE), but that is so anoying, that we
define it as returning int, which is ok on arm (32-bit).
_CRTIMP void* __cdecl __MINGW_NOTHROW fileno (FILE*); */
_CRTIMP int __cdecl __MINGW_NOTHROW fileno (FILE*);
#endif
Not sure what to do with this.
Opinions anyone ?
