The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

INQUIRE POSTED STRUCTURES (PHOP,WSOP,*,*)

Purpose

Use Inquire Posted Structures to inquire the structure networks which have been identified for display on the specified workstation by the Post Structure 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 one of the following errors:

3
Function Requires State (PHOP,WSOP,*,*)
54
Specified Workstation Is Not Open
59
Specified Workstation Does Not Have Output Capability

Language Bindings

C

pinq_posted_structs (ws_id, num_elems_appl_list, start_ind, err_ind, struct_ids, num_elems_impl_list)

Input Parameters

Pint ws_id
Workstation identifier.

Pint num_elems_appl_list
Number of elements in the application list (>=0).

Pint start_ind
Starting index (>=0).

Output Parameters

Pint *err_ind
Error indicator.

Pposted_struct_list *struct_ids
List of structures posted to the workstation.

Pint *num_elems_impl_list
Number of elements in the implementation list.

FORTRAN

PQPOST (wkid, n, errind, number, strid, priort)

Input Parameters

integer wkid
Workstation identifier.

integer n
List element requested (>=0).

Output Parameters

integer errind
Error indicator.

integer number
Number of structures posted to the workstation.

integer strid
Identifier of the nth structure posted to the workstation.

real priort
Input priority of the nth structure posted to the workstation.

Errors

None
