- *   xMemAlloc() is a clustered, remembering memory management routine.  *
- *   It uses its own tables for free and used memory blocks on private   *
- *   memory area. With xMemFree(), you can free this memory likewise     *
- *   the C free() routine, with xMemFreeAll() all memory at once.        *
- *   By changing the current remember key with xSetRemember() you can    *
- *   define a local memory area, which can be freed by only one call of  *
- *   xMemFreeAll() (see xSetRemember() / xGetRemember()).                *
- *                                                                       *
