NAME
	  glGetMapdv, glGetMapfv, glGetMapiv - return evaluator
	  parameters


     C SPECIFICATION
	  void glGetMapdv( GLenum target,
			   GLenum query,
			   GLdouble *v )
	  void glGetMapfv( GLenum target,
			   GLenum query,
			   GLfloat *v )
	  void glGetMapiv( GLenum target,
			   GLenum query,
			   GLint *v )


     PARAMETERS
	  target  Specifies the	symbolic name of a map.	 Accepted
		  values are GL_MAP1_COLOR_4, GL_MAP1_INDEX,
		  GL_MAP1_NORMAL, GL_MAP1_TEXTURE_COORD_1,
		  GL_MAP1_TEXTURE_COORD_2, GL_MAP1_TEXTURE_COORD_3,
		  GL_MAP1_TEXTURE_COORD_4, GL_MAP1_VERTEX_3,
		  GL_MAP1_VERTEX_4, GL_MAP2_COLOR_4, GL_MAP2_INDEX,
		  GL_MAP2_NORMAL, GL_MAP2_TEXTURE_COORD_1,
		  GL_MAP2_TEXTURE_COORD_2, GL_MAP2_TEXTURE_COORD_3,
		  GL_MAP2_TEXTURE_COORD_4, GL_MAP2_VERTEX_3, and
		  GL_MAP2_VERTEX_4.

	  query	  Specifies which parameter to return.	Symbolic names
		  GL_COEFF, GL_ORDER, and GL_DOMAIN are	accepted.

	  v	  Returns the requested	data.

     DESCRIPTION
	  glMap1 and glMap2 define evaluators.	glGetMap returns
	  evaluator parameters.	 target	chooses	a map, query selects a
	  specific parameter, and v points to storage where the	values
	  will be returned.

	  The acceptable values	for the	target parameter are described
	  in the glMap1	and glMap2 reference pages.

	  query	can assume the following values:

	  GL_COEFF	 v returns the control points for the
			 evaluator function.  One-dimensional
			 evaluators return order control points, and
			 two-dimensional evaluators return
			 uorderxvorder control points.	Each control
			 point consists	of one,	two, three, or four
			 integer, single-precision floating-point, or
			 double-precision floating-point values,
			 depending on the type of the evaluator.  The
			 GL returns two-dimensional control points in
			 row-major order, incrementing the uorder
			 index quickly and the vorder index after each
			 row.  Integer values, when requested, are
			 computed by rounding the internal floating-
			 point values to the nearest integer values.

	  GL_ORDER	 v returns the order of	the evaluator
			 function.  One-dimensional evaluators return
			 a single value, order.	The initial value is
			 1.  Two-dimensional evaluators	return two
			 values, uorder	and vorder. The	initial	value
			 is 1,1.

	  GL_DOMAIN	 v returns the linear u	and v mapping
			 parameters.  One-dimensional evaluators
			 return	two values, u1 and u2, as specified by
			 glMap1.  Two-dimensional evaluators return
			 four values (u1, u2, v1, and v2) as specified
			 by glMap2.  Integer values, when requested,
			 are computed by rounding the internal
			 floating-point	values to the nearest integer
			 values.

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

     ERRORS
	  GL_INVALID_ENUM is generated if either target	or query is
	  not an accepted value.

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