The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE STRUCTURE IDENTIFIERS (PHOP,*,*,*)

Purpose

Use Inquire Structure Identifiers to inquire the currently existing structure identifiers in the centralized structure store.

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:

2
Function Requires State (PHOP,*,*,*)
