How do I write this C call in Cocoa?

What about
float Y[2];
float X[2];
X[0] = 5;
X[1] = 1;
Y[0] = 2;
X[1] = 3;
vertices(X, Y, 2);
/* Other file */
void vertices(float xVert[], float yVert[], int TOTAL)
{
int i;
for(i=0; i < TOTAL; i++) {
glTranslatef(xVert[i], yVert[i], 0.0);
}
}
? I guess that would be the simplest way. And since it is self-evidently a
ported code, it seems quite improbable the lact of
encapsulation/polymorphism/inheritance would really matter.
OTOH, if you wanted to refactor badly, you might also consider NSPoints
and similar beasts (incl. NSArrays, which depends on the efficiency needed)
.
Finally, if you insist,
- (void)verticesX:(float[])xVert Y:(float[])yVert T:(int)TOTAL;
might work (never tried), whilst
- (void)verticesX:(float*)xVert Y:(float*)yVert T:(int)TOTAL;
would work for sure (also never tried, but many times used similar
constructions).
