gethitcode(3G)							gethitcode(3G)

NAME
     gethitcode - returns the current hitcode

C SPECIFICATION
     long gethitcode()

PARAMETERS
     none

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, with one bit for each clipping plane:

		  5	   4	    3	     2	      1	       0
	       _____________________________________________________
		 far	  near	   top	   bottom   right     left
	       _____________________________________________________
	       |
		       |

SEE ALSO
     clearhitcode, gselect, pick

NOTES
     This routine is available only in immediate mode.

     The symbolic values for the hitcode bits shown above are defined in
     <gl/get.h>.

     This routine only functions on IRIS-4D B and G models, and therefore we
     advise against its use in new development.
