INQUIRE DYNAMICS OF STRUCTURES (PHOP,*,*,*)

Purpose

Use Inquire Dynamics of Structures to inquire the dynamic modification supported by the specified workstation for the following categories of picture changes:

• structure content modification
• post structure
• unpost structure
• delete structure
• reference modification (structure identifier changes).

Possible dynamic modifications include: IMPLICIT REGENERATION (IRG), meaning that implicit regeneration is necessary; IMMEDIATELY (IMM), meaning that the action is performed immediately; and CAN BE SIMULATED (CBS), meaning that the change can be simulated. If a category has a dynamic modification of IRG or CBS, it is still possible that your application can immediately execute some changes correctly if the state of the picture allows it. (For example, if no structures are posted, most changes can be executed immediately.)

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:
