I decide to rewrite my graphics library using 100% ANSI C only.
The problem is that the DJGPP throws a bunch of error messages when I try
to use
__tb or __dpmi_regs, and __djgpp_conventional_base.
The following code works perfectly fine without the -ansi option:
#include <dpmi.h>
#include <go32.h>
VESA_INFO GetVesaInfo(void)
{
/* Determines if VESA compatible by returning
* a structure contain information about the video card.
*/
static VESA_INFO Info;
static __dpmi_regs r;
r.x.ax = 0x4F00;
r.x.di = __tb & 0x0F;
r.x.es = (__tb >> 4) & 0xFFFF;
dosmemput(&Info, sizeof(VESA_INFO), __tb);
__dpmi_int(0x10, &r);
dosmemget(__tb, sizeof(VESA_INFO), &Info);
return Info;
}
How do I rewrite this so it will compile (and work) under the -ansi option?
