OSHeapHandler OS_CreateHeap( OSArenaId id, void* start, void* end );
This function creates a heap in the specified arena. The arena must have
memory allocated with the OS_InitAlloc function and then be initialized in
advance.
The arena is specified by an arena ID id. For information about this value see OS_InitArena. The region for the heap is from start to end. The end address is +1 from the actual end position.
OS_CreateHeap( OS_ARENA_MAIN, (void*)0x2030000, (void*)0x2040000 ), the 0x10000 bytes of the 0x2030000 – 0x203FFFF will be used as the heap region.
id |
The arena ID of an arena in which you are going to create a heap. |
start |

In the case that it was possible to create a heap, a value of 0 or greater will be returned, which is the handle to the heap.
In the case that it was not possible to create a heap, a -1 is returned.
