Hi,
I'm trying out some basic graphics in DJGPP using a tutorial I found ( and
when compiling RHIDE gives me the error:
Error: cannot convert `regs' from type `REGS' to type `REGS *'
I was wondering if anyone could tell me what this means and (hopefully) how
to fix it... Here is the source:

#include <dos.h>
#include <bios.h>
#include <dpmi.h>
#include <stdio.h>
#include <conio.h>
#include <math.h>
#include <stdlib.h>
#include <go32.h>
#include <pc.h>
#include <sys/nearptr.h>

// Init VGA Mode Function Prototype
int init_vga_mode(void);

// Global Variables
char *vgamemory;
char *vgabuffer;

// Main Function
void main()
{
init_vga_mode();
}

// Init VGA Mode Function
int init_vga_mode(void)
{
union REGS regs;
__djgpp_nearptr_enable();
vgamemory=(char *)(0xA0000 + __djgpp_conventional_base);
if((vgabuffer=(char *)malloc(320*200))==NULL)
{
return(1);
}
regs.h.ah=0x00; file://Procedure 0x00: Set Video Mode
regs.h.al=0x13; file://The mode to set (0x# = #h)
int86(0x10, regs, regs); file://Call BIOS intr 0x10
return(0);
}
