Function BridgePrepareReallocAligned 

pub unsafe extern "C" fn BridgePrepareReallocAligned(
    old_ptr: *mut c_void,
    new_size: size_t,
    alignment: size_t,
    old_size: *mut size_t,
) -> *mut c_void

Prepare to reallocate previously allocated memory.

Caller should do the real data migration if a returned pointer is not the same as old_ptr. Client should copy bytes manually and then free old_ptr.

The pointer old_ptr must have been allocated before.

The alignment must match the one used to allocate old_ptr.

Returns null pointer if allocation failed or new_size is 0.

old_size will be set to the original size of the memory block.
