    When you request an AST under VMS, you pass in the address of
    you own handler function. This function is "called" by the system
    when the AST completes. A handler function accepts as its arguments
    the address of a status structure (the AST completion code, number of
    bytes transferred, etc ...) and an optional argument passed in
    during the original AST request. This handler function can then process
    the results of the AST, resubmit the AST - whatever. Quite elegant really.

    But I digress, NT is an incomplete imitation of VMS - so I guess it does
    something similar.
