     <STRONG>NAME</STRONG>
	  <STRONG>glEdgeFlag,</STRONG> <STRONG>glEdgeFlagv</STRONG> - flag edges as either boundary or
	  nonboundary


     <STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
	  void <STRONG>glEdgeFlag</STRONG>( GLboolean <EM>flag</EM> )


     <STRONG>PARAMETERS</STRONG>
	  <EM>flag</EM>	Specifies the current edge flag	value, either <STRONG>GL_TRUE</STRONG>
		or <STRONG>GL_FALSE</STRONG>. The initial value is <STRONG>GL_TRUE</STRONG>.

     <STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
	  void <STRONG>glEdgeFlagv</STRONG>( const GLboolean *<EM>flag</EM> )


     <STRONG>PARAMETERS</STRONG>
	  <EM>flag</EM> Specifies a pointer to an array that contains a single
	       boolean element,	which replaces the current edge	flag
	       value.

     <STRONG>DESCRIPTION</STRONG>
	  Each vertex of a polygon, separate triangle, or separate
	  quadrilateral	specified between a <STRONG>glBegin</STRONG>/<STRONG>glEnd</STRONG> pair is
	  marked as the	start of either	a boundary or nonboundary
	  edge.	 If the	current	edge flag is true when the vertex is
	  specified, the vertex	is marked as the start of a boundary
	  edge.	 Otherwise, the	vertex is marked as the	start of a
	  nonboundary edge.  <STRONG>glEdgeFlag</STRONG>	sets the edge flag bit to
	  <STRONG>GL_TRUE</STRONG> if <EM>flag</EM> is <STRONG>GL_TRUE</STRONG>, and to <STRONG>GL_FALSE</STRONG> otherwise.

	  The vertices of connected triangles and connected
	  quadrilaterals are always marked as boundary,	regardless of
	  the value of the edge	flag.

	  Boundary and nonboundary edge	flags on vertices are
	  significant only if <STRONG>GL_POLYGON_MODE</STRONG> is set to	<STRONG>GL_POINT</STRONG> or
	  <STRONG>GL_LINE</STRONG>.  See	<STRONG>glPolygonMode</STRONG>.

     <STRONG>NOTES</STRONG>
	  The current edge flag	can be updated at any time.  In
	  particular, <STRONG>glEdgeFlag</STRONG> can be	called between a call to
	  <STRONG>glBegin</STRONG> and the corresponding	call to	<STRONG>glEnd</STRONG>.
