INTEGER*4 FUNCTION GETMAP

Description

The getmap subroutine returns the identification number of the current color map. In multimap mode, there are 16 small, independent color maps; therefore, the getmap subroutine returns a value in the range 0 to 15. In onemap mode, the getmap subroutine returns 0 (zero).

Note: This subroutine cannot be used to add to a display list.

Return Value

The number of the current color map, a value from 0 to 15.

Implementation Specifics

This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
