SYNOPSIS
       #include 

       CGbuffer cgGLCreateBuffer( CGcontext context,

                                  const void *data,
                                  GLenum bufferUsage );


PARAMETERS
     context The context to which the new buffer will be added.

     size    The length in bytes of the buffer to create.

     data    The inital data to be copied into the buffer. NUL

     bufferUsage
             One of the usage flags specified as valid for
             glBufferData.

RETURN VALUES
     Returns a CGbuffer handle on success.

     Returns NUL if any error occurs.

DESCRIPTION
     cgGLCreateBuffer creates an OpenGL buffer object.

EXAMPLES
       CGbuffer myBuffer = cgGLCreateBuffer( myCgContext, sizeof( float ) * 16,
                                             myData, GLSTATICDRAW );
