The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE CURRENT ELEMENT TYPE AND SIZE (PHOP,*,STOP,*)

Purpose

Use Inquire Current Element Type and Size to inquire the type and size of the current element.

The graPHIGS API returns the element of the structure element pointed to by the element pointer. If elements of this type have no associated values, then the graPHIGS API returns a value of zero in the element size parameter. If the element pointer is currently zero, then the graPHIGS API returns a NIL value in the element type parameter. To retrieve the element contents, use the Inquire Current Element Content subroutine

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameters. If the information is unavailable, then the values returned in the output parameters are unpredictable and the graPHIGS API sets the error indicator to the following error:
