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 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.  Call noport at the beginning of a graphics program; then call getport to do a graphics initialization. 

The system ignores noport if getport is not called or the window manager is not running.
