Well, if you are using Win32Lib then you could do something like this:

-- define SECURITY_ATTRIBUTES structure
constant
  SAnLength = w32allot( DWord ),
  SAlpSecurityDescriptor = w32allot( Ptr ),
  SAbInheritHandle = w32allot( UInt ),
  SIZEOF_SECURITY_ATTRIBUTES = w32alloted_size()

Then use other memory management functions to store and peek values to 
the structure.  (w32acquire_mem, w32store, w32fetch, w32release_mem, 
etc.).

Yah... but what pointer do i give it?
The other thing... this program has (so far) NOT required win32lib,
and for portability reasons, i'd like it to stay that way....
