NAME

       glEdgeFlagPointer - define an array of edge flags

C SPECIFICATION

       void glEdgeFlagPointer( GLsizei stride,
			       const GLboolean *pointer )

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.

       pointer	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 boolean 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 pointer 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 undefined.

       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
