C++ (Cpp) update_xmalloc_stat_free Examples

Example #1

File: malloc_hook.c Project: wangdali/skynetw

inline static void*
clean_prefix(char* ptr) {
	size_t size = je_malloc_usable_size(ptr);
	uint32_t *p = (uint32_t *)(ptr + size - sizeof(uint32_t));
	uint32_t handle;
	memcpy(&handle, p, sizeof(handle));
	update_xmalloc_stat_free(handle, size);
	return ptr;
}
