[MiNT] MiNTlibs for PureC

Hallo Thomas,

Agreed!

The reason for this behaviour is to be found in fcntl.h #87:

/* smallest valid gemdos handle */
/* note handle is only word (16 bit) negative, not long negative,
   and since Fopen etc are declared as returning long in osbind.h
   the sign-extension will not happen -- thanks ers
*/
#ifdef __MSHORT__
#define __SMALLEST_VALID_HANDLE (-3)
#else
#define __SMALLEST_VALID_HANDLE (0)
#endif

So the -1 would have to be rplaced by __SMALLEST_VALID_HANDLE -1
whenever a file-handle is returned !?

Sure there are devices with negative handles but are they returned by
open et al and/or does mintlib have to support this?

bye, Helmut
