Description

pset_int_colr sets the color that Digital PHIGS uses to fill interiors. Depending on the edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer. The pointer then points to the new set interior color element.

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
