SPECIFICATION

C
long gethitcode()

FORTRAN
integer*4 function gethit()

Pascal
function gethitcode: longint;

DESCRIPTION

gethitcode returns the global variable hitcode, which keeps a cumulative record of clipping plane hits.  It does not change the hitcode value. 

The hitcode is a 6-bit number (see below), with one bit for each clipping plane.  (Systems configured without near-far clipping return zeros (0s) for the near and far clipping planes.)
