Function Documentation

void debug_destroyAllocator (  allocator_t *  debugAllocator  )

Destroy a debug allocator and check it for leaks. Parameters: debugAllocator,:  an allocator as initialized by debug_initAllocator

void debug_free (  void *  ptr, size_t  intSize, void *  debugAllocations )

Debug free function, to free memory allocated by debug_malloc. Parameters: ptr,:  memory to deallocate. intSize,:  size to deallocate debugAllocations,:  all the allocations.

int32_t* debug_malloc (  size_t  intSize, void *  debugAllocations )

Debug allocator function based on malloc. Parameters: intSize,:  size to allocate in ints debugAllocations,:  a debug_allocation_t** Returns: int32_t[intSize] allocated by malloc
