The WOWGlobalLock16 function locks a global memory object and returns a pointer to the first byte of the object's memory block. This function can only be called in the context of a thunk.
DWORD WINAPI WOWGlobalLock16(
WORD hMem
);
Parameters
- hMem
[in] Handle to the object in the 16-bit global heap. This value must have been obtained from the WOWGlobalAlloc16 or WOWGlobalAllocLock16 function.
