Defines an array of edge flags.
OpenGL C bindings library: libGL.a
void glEdgeFlagPointer(GLsizei stride, const GLvoid *pointer)
The glEdgeFlagPointer subroutine specifies the location and data format of an array of Boolean edge flags to use when rendering. The stride parameter gives the byte stride from one edge flag to the next allowing vertexes 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 vertexes and vertex attributes and glDrawElements to construct a sequence of primitives by indexing vertexes and vertex attributes.
The glEdgeFlagPointer subroutine 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 glBegin and the corresponding glEnd, but an error may or may not be generated. If an error is not generated, the operation is undefined.
The glEdgeFlagPointer subroutine is typically implemented on the client side with no protocol.
Since the edge flag array parameters are client side state, they are not saved or restored by glPushAttrib and glPopAttrib. Use glPushClientAttrib and glPopClientAttrib instead.
The glEdgeFlagPointer subroutine is not included in display lists.
GL_INVALID_ENUM is generated if stride is negative.
