	  void <STRONG>glGetMapdv</STRONG>( GLenum <EM>target</EM>,
			   GLenum <EM>query</EM>,
			   GLdouble *<EM>v</EM> )
	  void <STRONG>glGetMapfv</STRONG>( GLenum <EM>target</EM>,

			   GLenum <EM>query</EM>,
			   GLint *<EM>v</EM> )


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

	  <EM>query</EM>	  Specifies which parameter to return.	Symbolic names
		  <STRONG>GL_COEFF</STRONG>, <STRONG>GL_ORDER</STRONG>, and <STRONG>GL_DOMAIN</STRONG> are	accepted.

	  <EM>v</EM>	  Returns the requested	data.

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

	  The acceptable values	for the	<EM>target</EM> parameter are described
	  in the <STRONG>glMap1</STRONG>	and <STRONG>glMap2</STRONG> reference pages.

	  <EM>query</EM>	can assume the following values:

	  <STRONG>GL_COEFF</STRONG>	 <EM>v</EM> 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.

	  <STRONG>GL_ORDER</STRONG>	 <EM>v</EM> 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.

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

     <STRONG>NOTES</STRONG>
	  If an	error is generated, no change is made to the contents
	  of <EM>v</EM>.

     <STRONG>ERRORS</STRONG>
	  <STRONG>GL_INVALID_ENUM</STRONG> is generated if either <EM>target</EM>	or <EM>query</EM> is
	  not an accepted value.

	  <STRONG>GL_INVALID_OPERATION</STRONG> is generated if <STRONG>glGetMap</STRONG>	is executed
	  between the execution	of <STRONG>glBegin</STRONG> and the corresponding
	  execution of <STRONG>glEnd</STRONG>.
