-/**
- * \defgroup memb Memory block management functions
- *
- * The memory block allocation routines provide a simple yet powerful
- * set of functions for managing a set of memory blocks of fixed
- * size. A set of memory blocks is statically declared with the
- * MEMB() macro. Memory blocks are allocated from the declared
- * memory by the memb_alloc() function, and are deallocated with the
- * memb_free() function.
- *
- * \note Because of namespace clashes only one MEMB() can be
- * declared per C module, and the name scope of a MEMB() memory
- * block is local to each C module.
- *
- * The following example shows how to declare and use a memory block
- * called "cmem" which has 8 chunks of memory with each memory chunk
- * being 20 bytes large.
- *

- * Declare a memory block.
- *
- * This macro is used to staticall declare a block of memory that can
- * be used by the block allocation functions. The macro statically
- * declares a C array with a size that matches the specified number of
- * blocks and their individual sizes.
- *
- * Example:
- \code
-MEMB(connections, sizeof(struct connection), 16);
- \endcode
- *
- * \param name The name of the memory block (later used with
- * memb_init(), memb_alloc() and memb_free()).
- *
- * \param size The size of each memory chunk, in bytes.
- *
- * \param num The total number of memory chunks in the block.
