4.8.3 __Heap_Descriptor

You must define your own implementation of the abstract data type for heap. A C header

file describing this abstract data type is provided in

rt_heap.h

. You must provide the

interior definition of the structure so that the other functions can find the heap data.

Typical contents are given in Example 4-17.

Example 4-17 Heap_Descriptor

struct __Heap_Descriptor {

void *my_first_free_block;

void *my_heap_limit;

}

Your heap descriptor is set by

__Heap_Initialize()

and is passed to the other heap

functions, for example

__Heap_Alloc()

and

__Heap_Free()
