- * @file chmemcore.c
- * @brief Core memory manager code.
- *
- * @addtogroup memcore
- * @details Core Memory Manager related APIs and services.
- * <h2>Operation mode</h2>
- * The core memory manager is a simplified allocator that only
- * allows to allocate memory blocks without the possibility to
- * free them.<br>
- * This allocator is meant as a memory blocks provider for the
- * other allocators such as:
- * - C-Runtime allocator (through a compiler specific adapter module).
- * - Heap allocator (see @ref heaps).
- * - Memory pools allocator (see @ref pools).
- * .
- * By having a centralized memory provider the various allocators
- * can coexist and share the main memory.<br>
- * This allocator, alone, is also useful for very simple
- * applications that just require a simple way to get memory
- * blocks.
- * @pre In order to use the core memory manager APIs the @p CH_USE_MEMCORE
- * option must be enabled in @p chconf.h.
