||
Parameters |
obj is a pointer to the object that contains the primitive whose area is to be measured prim is a pointer to the closed primitive whose area is to be measured area is a pointer to the double that is to receive the calculated area
|
|
||
Return Value |
surface_area_prim returns TRUE if all 3 parameters are valid, and if prim is a pointer to a closed primitive. It returns FALSE otherwise.
