stack overhead on recursion

[boker]

plz help, i have problem with my program
i'm using recursion to do flood fill algorithm
void flood (int x, int y, int fillcolor,int oldcolor) {
putixel(x+1,y,fillcolor);
putixel(x-1,y,fillcolor);
putixel(x,y+1,fillcolor);
putixel(x,y-1,fillcolor);
}
that recursion algorithm will fit with a small object but not with large object
it seems a stack problem and result illegal instruction
any suggestion to fix?

Read this link: http://en.wikipedia.org/wiki/Flood_fill

Basically it implements a floodfill but it doesn't use recursion for the east-west
direction but just applies a clever iterative approach (it searches for boundary
colours in the east-west direction).

kind regards,
