Billy ONeal - Right. My concern is about how that memory is freed. LocalAlloc is only allocating memory on the device.

So, if I allocate it with new or malloc can it be safely freed with LocalFree? Absolutely not, Paul. Things allocated with new should only be released with delete. Likewise, malloc and free form a pair, as do LocalAlloc and LocalFree. Never mix and match. From the page you link to n your comment to miked's response "In the linear Windows Embedded CE API environment, there is no difference between the local heap and the global heap.

It doesn't look like LocalLock is defined, either. LHND is for when you want the memory-allocation function to return a movable handle — that's what the HND name indicates. But Windows Mobile doesn't support memory handles here.

Post by Gakuren Ko As my understanding, which memory allocation API should be used depends on the size you need to allocate and how you use the memory you have allocated.

LocalAlloc and malloc allocate memory from process local heap which resides within 32MB process slot, while VirtualAlloc allocate memory from virtual space which could be process's free virtual space in 32MB prcess slot or shared memory which is outside 32MB process slot.

The number of bytes to allocate. If the function fails, the return value is NULL. To get extended error information, call GetLastError. Windows memory management does not provide a separate local heap and global heap. Therefore, the LocalAlloc and GlobalAlloc functions are essentially the same.

They should be avoided unless documentation specifically states that they should be used. New applications should use the heap functions unless the documentation specifically states that a local function should be used. For example, some Windows functions allocate memory that must be freed with LocalFree. Because NULL is used to indicate an error, virtual address zero is never allocated. It is, therefore, easy to detect the use of a NULL pointer.
