- * @file    chmempools.c

- * @brief   Memory Pools code.

- *

- * @addtogroup pools

- * @details Memory Pools related APIs and services.

- *          <h2>Operation mode</h2>

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

- *          <b>constant time</b> and reliably without memory fragmentation

- *          problems.<br>

- *          Memory Pools do not enforce any alignment constraint on the

- *          contained object however the objects must be properly aligned

- *          to contain a pointer to void.

- * @pre     In order to use the memory pools APIs the @p CH_CFG_USE_MEMPOOLS option

- *          must be enabled in @p chconf.h.

- * @note    Compatible with RT and NIL.
