Specifies that a program does not require a window.
void noport( )
The noport subroutine specifies that a graphics program does not need screen space, and therefore does not require a window. This is useful for programs that only read or write the color map. Call this subroutine at the beginning of a graphics program, then call the winopen subroutine to initialize graphics.
The noport subroutine is ignored without a call to the winopen subroutine.
Note: This subroutine cannot be used to add to a display list.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
