 *          The Memory Pools APIs allow to allocate/free fixed size objects in

 *          problems.<br>
 *          Memory Pools do not enforce any alignment constraint on the

 *          to contain a pointer to void.
 * @pre     In order to use the memory pools APIs the @p CH_USE_MEMPOOLS option
 *          must be enabled in @p chconf.h.
