The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE SET OF WORKSTATIONS TO WHICH POSTED (PHOP,*,*,*)

Purpose

Use Inquire Set of Workstations to Which Posted to inquire the list of workstations to which the specified structure is posted.

This subroutine returns the number of workstations and the workstation identifiers to which the specified structure is posted.

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 one of the following errors:

2
Function Requires State (PHOP,*,*,*)
201
Specified Structure Does Not Exist
