I'm writing a fairly simple program for a school assignment.
All I have to do is implement a few simple graphics algorithms,
bresh. line drawing, ellipse, polygon, and a boundary fill.
I have all the other things working fine, but this function
seems to cause major problem.
The funny thing is it will seem to work right for a fraction of a
second, but a bit into the fill, it will crash. Sometimes my computer
spontaneously reboots, sometimes I'll get a hard lock, or a GPF.
So, can anyone tell me why this code does this?
BTW, if I comment out 2 of the calls to boundfill in boundfill,
it will fill a quarter of the area without a problem...
void boundfill(int x, int y, int fill, int bound)
{
int cur;
cur=getpixel(screen,x,y);
if ((cur!=bound) && (cur!=fill))
{
putpixel(screen,x,y,fill);
boundfill(x+1,y,fill,bound);
boundfill(x-1,y,fill,bound);
boundfill(x,y+1,fill,bound);
boundfill(x,y-1,fill,bound);
} //if
}
this is really bugging me,
I'd appreciate any suggestions,
Carl
