 *  MemError()
 *  
 *  Summary:
 *    Determines if an applicationÕs last direct call to a Memory
 *    Manager function executed successfully.
 *  
 *  Discussion:
 *    MemError() yields the result code produced by the last Memory
 *    Manager function your application called directly, and resets
 *    MemError() to return noErr in the future. MemError() is useful
 *    during application debugging. You might also use MemError as one
 *    part of a memory-management scheme to identify instances in which
 *    the Memory Manager rejects overly large memory requests by
 *    returning the error code memFullErr.
 *    
 *    To view the result codes that MemError() can produce, see "Memory
 *    Manager Result Codes".
 *    
 *    Do not rely on MemError() as the only component of a
 *    memory-management scheme. For example, suppose you call NewHandle
 *    or NewPtr and receive the result code noErr, indicating that the
 *    Memory Manager was able to allocate sufficient memory. In this
 *    case, you have no guarantee that the allocation did not deplete
 *    your applicationÕs memory reserves to levels so low that simple
 *    operations might cause your application to crash. Instead of
 *    relying on MemError(), check before making a memory request that
 *    there is enough memory both to fulfill the request and to support
 *    essential operations.
 *    
 *    On Mac OS X 10.3 and later, the value of MemError() is kept for
 *    each thread; prior to Mac OS X 10.3.  MemError() is global to the
 *    application.  Because of this, and other problems, the Memory

 *  LMGetMemErr()
 *  
 *  Summary:
 *    Returns the result of the last Memory Manager function, without
 *    clearing the value like MemError() does.
 *  
 *  Discussion:
 *    LMGetMemErr yields the result code produced by the last Memory
 *    Manager function your application called directly. Unlike
 *    MemError(), this function does not reset the stored value, so
 *    subsequent calls to LMGetMemErr() will still return this value
 *    until the next Memory Manager routine is called or until
 *    MemError() is called to reset the value. LMGetMemErr is useful
 *    during application debugging. You might also use this value as
 *    one part of a memory-management scheme to identify instances in
 *    which the Memory Manager rejects overly large memory requests by
 *    returning the error code memFullErr.
 *    
 *    To view the result codes that MemError() can produce, see "Memory

 *    On Mac OS X 10.3 and later, the value of MemError() is kept for

 *  
 *  Summary:

 *  Discussion:
 *    The HLock procedure locks the relocatable block to which h is a
 *    handle, preventing it from being moved within its heap zone. If
 *    the block is already locked,HLock does nothing.
 *    
 *    On Mac OS X, the behaviour of the Memory Manager and of heaps in
 *    general is different than on Mac OS 9.x and earlier. In
 *    particular, the heap on Mac OS X is never purged or compacted. 
 *    Therefore, an unlocked handle will never be relocated except as a
 *    result of a direct action by something calling SetHandleSize() or
 *    by using a function like PtrAndHand() which implicitly resizes
 *    the handle to append data to it.  Because of this, most locking
 *    and unlocking of handles is unnecessary on Mac OS X, and the use
 *    of HLock() and other functions is being deprecated.  If you
 *    define a macro named __MAC_OS_X_MEMORY_MANAGER_CLEAN__ to 1 in
 *    your sources before you include MacMemory.h, then HLock() and
 *    several other functions will become empty operations, removing
 *    the overhead of a function call.
 *    
 *    However, some applications are relying on the behavior that
 *    resizing a locked handle produces an error, or tracking the state
 *    of the locked bit for a give handle via the HGetState() function.
 *     Applications which rely on this can not use

 *  Summary:

 *  
 *  Discussion:
 *    The EmptyHandle function purges the relocatable block whose
 *    handle is h and sets the handleÕs master pointer to NULL. The
 *    EmptyHandle function allows you to free memory taken by a
 *    relocatable block without freeing the relocatable blockÕs master

 *    
 *    Note that if there are multiple handles to the relocatable block,
 *    then calling the EmptyHandle function empties them all, because
 *    all of the handles share a common master pointer. When you later
 *    use ReallocateHandle to reallocate space for the block, the
 *    master pointer is updated, and all of the handles reference the

{
 *  HGetState()
 *  
 *  Summary:
 *    Get the current state of the handle's locked, purgeable, and R
 *    bits
 *  
 *  Discussion:
 *    The HGetState function returns a signed byte (char) containing
 *    the flags of the master pointer for the given handle. You can
 *    save this byte, change the state of any of the flags using the
 *    functions described in this section, and then restore their
 *    original states by passing the byte to the HSetState
 *    function.
 *    
 *    You can use bit-manipulation functions on the returned signed
 *    byte to determine the value of a given attribute.
 *    Currently the following bits are used:
 *    kHandleIsResourceBit    - if set, handle is a resource
 *     kHandlePurgeableBit - if set, handle is purgeable
 *     kHandleLockedBit - if set, handle is locked
 *    On Mac OS X and later, heaps are never purged, so the purgeable
 *    bit is used but its setting is essentially ignored. Also, since
 *    heaps are never compacted, and therefore the only time a handle
 *    moves is when that handle is resized, the danger of using
 *    defererenced handles is lower and so handles likely do not need
 *    to be locked as often. Because of this, the state for a handle is
 *    less useful, and HGetState() and other functions is being
 *    deprecated.  If you define a macro named
 *    __MAC_OS_X_MEMORY_MANAGER_CLEAN__ in your sources before you
 *    include MacMemory.h, then HGetState() and several other functions
 *    will become empty operations, removing the overhead of a function
 *    call.
 *    
 *    However, some applications may depend on the state bits of a
 *    handle being correct or changing as functions like HLock(), etc.,
 *    are called.  Applications which rely on this can not use
 *    __MAC_OS_X_MEMORY_MANAGER_CLEAN__.

    Beginning in Mac OS X Tiger, BlockMove, BlockMoveData, BlockMoveUncached,
    BlockMoveDataUncached, BlockZero, and BlockZeroUncached are inlined to a
    direct call to the posix memmove or bzero functions; this allows the 
    compiler to optimize in some cases.
    
    However, CarbonCore.framework still exports functions with these names,
    both so old code which linked them there will run and to support

 *  Summary:

 *    The PtrAndHand function takes the number of bytes specified by

 *  Mac OS X threading:

 *    ptr1:
 *      a pointer to the beginning of the data that the Memory Manager
 *      is to concatenate onto the end of the relocatable block.
 *

 *      Manager expands so that it can concatenate the information from
