 * ReadRequest : returns one request from the buffer
 *
 * This "routine" is fairly simple (so we code it as a macro):
 * Look at the start of the "buffer" and determine the length of the next
 * request (the request length is always stored in the 3rd byte)
 * Compare this length with "size" to see if the buffer contains the
 * whole request.
 * If so, return the address of the buffer,
 * otherwise return NULL
 *****************************************************************/

    ( ( ( size == 0 ) || ( ( ( ( xReq * )buffer )->length ) << 2 ) > size ) ? \
