  Name: resource.h

  Description:     Contains the function prototypes for the resource layer.

    $Log:   J:/LOGFILES/RESOURCE.H_V  $

   Rev 1.6   27 Aug 1992 10:31:32   CLIFF
Changed MAYN_OS2 to OS_OS2.

   Rev 1.5   02 Mar 1992 09:22:48   NED
finally got MemFill prototype right (!)

   Rev 1.4   02 Mar 1992 09:08:58   NED
re-added OS2_DMA_xfer() prototype for OS/2

   Rev 1.3   28 Feb 1992 19:28:14   CHARLIE
Did a VDEL on the previous Rev 1.3

Added prototype for SetIntVectors

Cannot add prototype for OS2_DMA_xfer because TDD_PTR is not yet defined
when this file is included

   Rev 1.2   28 Feb 1992 11:17:04   NED
fixed prototype for MemFill()

   Rev 1.1   25 Feb 1992 14:27:04   NED
fixed prototype

   Rev 1.0   17 Jul 1991 15:33:06   ED
Initial revision.
