Yes, at least the part with GL_TRIANGLE_STRIP. In case of "0" you can just return 0, no copying is needed.
case 0: return 0; break;
You're going to do that, just in a slightly different manner:
switch (nr) {
case 0: ovf = 0; break;
case 1: ovf = 1; break;
default: ovf = 2; break;
}
for (i = 0 ; i < ovf ; i++)
copy_vertex( rmesa, nr-ovf+i, tmp[i] );
return i; When nr == 0, ovf gets set to 0 and you do no iterations of the for loop. You'll then return i, which was initialized to 0.
