Int32 getgdesc(Int32 inquiry);
INTEGER *4 FUNCTION GETGDE(inquiry) INTEGER*4 inquiry
The getgdesc subroutine allows you to inquire about characteristics of the graphics system. The characteristics are all hardware characteristics; that is, the values returned do not change as the adapter is software reconfigured.
It is not necessary to open a GL window or call the ginit subroutine before using the getgdesc subroutine.
Note: This subroutine cannot be used to add to a display list.
| inquiry | Represents the characteristics about which you want to inquire. Inquiries are submitted using tokens. |
The value of the requested characteristic, or -1 if the request is not valid or cannot be determined. For a listing of return values for adapters, see the "Adapter Description Table for GL", Appendix B.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
| /usr/include/gl/gl.h | Contains C language constant and variable type definitions for GL. |
| /usr/include/gl/fgl.h | Contains FORTRAN constant and variable type definitions for GL. |
