NAME
       glEdgeFlagPointer - define an array of edge flags

C SPECIFICATION
       void glEdgeFlagPointer( GLsizei stride,
			       const GLvoid *ptr )

PARAMETERS
       stride  Specifies  the  byte offset between consecutive edge flags.  If
	       stride is 0 (the initial value), the edge flags are  understood
	       to be tightly packed in the array. The initial value is 0.

       ptr     Specifies  a  pointer  to the first edge flag in the array. The
	       initial value is zero.

DESCRIPTION
       glEdgeFlagPointer specifies the location and data  of an array of bool‐
       ean  edge flags to use when rendering. stride specifies the byte stride
       from one edge flag to the next allowing vertices and attributes	to  be
       packed into a single array or stored in separate arrays.	 (Single-array
       storage	may  be	 more	efficient   on	 some	implementations;   see
       glInterleavedArrays.)

       When  an	 edge  flag  array  is	specified, stride and ptr are saved as
       client-side state.

       To enable and disable the edge flag array, call glEnableClientState and
       glDisableClientState with the argument GL_EDGE_FLAG_ARRAY. If  enabled,
       the  edge  flag	array  is  used	 when glDrawArrays, glDrawElements, or
       glArrayElement is called.

       Use glDrawArrays to construct a sequence of primitives (all of the same
       type)  from  prespecified  vertex  and  vertex  attribute  arrays.  Use
       glArrayElement to specify primitives by indexing	 vertices  and	vertex
       attributes  and glDrawElements to construct a sequence of primitives by
       indexing vertices and vertex attributes.

NOTES
       glEdgeFlagPointer is available  only  if	 the  GL  version  is  1.1  or
       greater.

       The edge flag array is initially disabled and it won't be accessed when
       glArrayElement, glDrawElements or glDrawArrays is called.

       Execution  of glEdgeFlagPointer is not allowed between the execution of
       glBegin and the corresponding execution of glEnd, but an error  may  or
       may  not be generated. If no error is generated, the operation is unde‐
       fined.

       glEdgeFlagPointer is typically implemented on the client side.

       Edge flag array parameters are client-side state and are therefore  not
       saved	or    restored	 by   glPushAttrib   and   glPopAttrib.	   Use
       glPushClientAttrib and
       glPopClientAttrib instead.

ERRORS
       GL_INVALID_ENUM is generated if stride is negative.

ASSOCIATED GETS
       glIsEnabled with argument GL_EDGE_FLAG_ARRAY
       glGet with argument GL_EDGE_FLAG_ARRAY_STRIDE
       glGetPointerv with argument GL_EDGE_FLAG_ARRAY_POINTER
