GLGETCLIPPLANE()						GLGETCLIPPLANE()

NAME
     glGetClipPlane - return the coefficients of the specified clipping plane

C SPECIFICATION
     void glGetClipPlane( GLenum plane,
			  GLdouble *equation )

     delim $$

PARAMETERS
     plane     Specifies  a  clipping  plane.  The number of clipping planes de-
	       pends on the implementation, but at least six clipping planes are
	       supported.  They are identified by symbolic  names  of  the  form
	       GL_CLIP_PLANE$i$ where 0 <= $ i $ < GL_MAX_CLIP_PLANES.

     equation  Returns four double-precision values that are the coefficients of
	       the  plane  equation  of  plane	in eye coordinates.  The initial
	       value is (0, 0, 0, 0).

DESCRIPTION
     glGetClipPlane returns in equation the four coefficients of the plane equa-
     tion for plane.

NOTES
     It is always the case that GL_CLIP_PLANE$i$ = GL_CLIP_PLANE0 + $i$.

     If an error is generated, no change is made to the contents of equation.

ERRORS
     GL_INVALID_ENUM is generated if plane is not an accepted value.

     GL_INVALID_OPERATION is generated if glGetClipPlane is executed between the
     execution of glBegin and the corresponding execution of glEnd.
