//  Routine Description:
//
//      This routine is used to complete an IRP with the indicated
//      status.  It does the necessary raise and lower of IRQL.
//
//  Arguments:
//
//      Irp - Supplies a pointer to the Irp to complete
//
//      Status - Supplies the completion status for the Irp
//
//  Return Value:
//
//      None.
//

//
//  The following macros are used to establish the semantics needed
//  to do a return from within a try-finally clause.  As a rule every
//  try clause must end with a label call try_exit.  For example,
//
//      try {
//              :
//              :
//
//      try_exit: NOTHING;
//      } finally {
//
//              :
//              :
//      }
//
//  Every return statement executed inside of a try clause should use the
//  try_return macro.  If the compiler fully supports the try-finally construct
//  then the macro should be
//
//      #define try_return(S)  { return(S); }
//
//  If the compiler does not support the try-finally construct then the macro
//  should be
//
      #define try_return(S)  { S; goto try_exit; }
//

//
//  This macro returns TRUE if a flag in a set of flags is on and FALSE
//  otherwise.  It is followed by two macros for setting and clearing
//  flags
