EMPTY STRUCTURE

PEMPTY_STRUCT

CALL SEQUENCE

void pempty_struct(

Pint	struct_id	/* structure identifier 	*/

)

PHIGS STATE

EFFECT

EMPTY STRUCTURE destroys all elements in structure struct_id. Even when empty, the structure continues to exist and all the references made to it continue to exist.

If struct_id is the open structure, all its elements are destroyed and element pointer is set to zero. If struct_id does not designate any existing structure, then EMPTY STRUCTURE creates a new empty structure.

ERRORS
