   cc32lib.h -- header for a simple access library for the
                                     PCICC32 PCI to CAMAC Interface from ARW Elektronik

   (c) 2000 ARW Elektronik

   this source code is published under GPL (Open Source). You can use, redistrubute and
   modify it unless this header   is not modified or deleted. No warranty is given that
   this software will work like expected.
   This product is not authorized for use as critical component in life support systems
   wihout the express written approval of ARW Elektronik Germany.
 
   Please announce changes and hints to ARW Elektronik

   To use this library the module "pcicc32.o" have to be installed. There must be also a
   node which points with ist major number to the module and its minor number must equal
   the CC32 module number (Jumper J301 to J304).
   
   first steps derived from the LINUX pcicc32 library                   AR   16.03.2000
   added buffer, UNTIL_NOT_Q and AUTOREAD functionality                 AR   17.03.2001
   added interrupt handling (NT + 2000 only)                            AR   08.06.2002
