// SHAllocShared  - Allocates a handle (in a given process) to a copy of a
//                  memory block in this process.
// SHFreeShared   - Releases the handle (and the copy of the memory block)

// SHLockShared   - Maps a handle (from a given process) into a memory block
//                  in this process.  Has the option of transfering the handle
//                  to this process, thereby deleting it from the given process
// SHUnlockShared - Opposite of SHLockShared, unmaps the memory block
