setprimvertex

int  setprimvertex(int geohandle, int prim, int vtxofprim, int pt)

Rewires a specified vertex to a point number.

If the point number is -1, no rewiring is done.

If prim is -1, vtxofprim is treated as a linear index, and vice versa. Otherwise, the pair (prim, vtxofprim) is used to identify a vertex in a primitive’s vertex list.

Since this sets a vertex’s point, not a primitive’s vertex, it’s recommended to use the equivalent function setvertexpoint for clarity, instead.
