I am trying to figure out how to display a bmp without using allegro but
I can't quite seem to get it.  here is my code:

#include <stdio.h>
#include <sys/movedata.h>
#include <dpmi.h>

#define VGA_13h 0x13
#define TEXT 3

void set_mode(int mode)
     {
     __dpmi_regs r;
     r.x.ax = mode;
     __dpmi_int(0x10, &r);
     };

void main()
{
 char smiley[320*200];
 FILE *pict= fopen("C:\\Cstuff\\smibm.bmp","rb");
 set_mode(VGA_13h);

 dosmemput(pict+128,320*200,0xA0000);
 while(!kbhit());
 set_mode(TEXT);

}

It compiles and runs ok but what I see on the screen is not the bmp that
I'm trying to display.  I'm not sure if this is even the right approach
but if someone could tell me what I'm doing wrong (or not doing at all)
I would appreciate it.

Thanks
