NAME

noport - specifies that a program does not require a graphics port

SPECIFICATION

C
noport()

FORTRAN
subroutine noport

Pascal
procedure noport;

DESCRIPTION

noport specifies that a graphics program does not need any screen space and therefore does not need a graphics port from the window manager.  This is useful for programs that only read or write the color map.  This command is called at the beginning of a graphics program; a call to getport is still needed to do a graphics initialization.  If getport is not called or if the system is not running the window manager, noport is ignored.

NOTE

This command can be used only in immediate mode.
