//  Contents:   This file contains a set of routines for the management of
//              shared memory.
//
//  Functions:  SCHEDAllocShared: Allocates a handle (in a given process)
//                  to a copy of a memory block in this process.
//
//              SCHEDFreeShared: Releases the handle (and the copy of the
//                  memory block)
//
//              SCHEDLockShared: 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
//
//              SCHEDUnlockShared: Opposite of SCHEDLockShared, unmaps the
//                  memory block
