  File: pcioDrv.hh

  Author: Steven Legowik

  Description:
    Provides an easy to use interface to the pcio device
    driver.

    For improved compatability with the old io access functions
    (declared in pcio.h) and ease of use, I have rewritten the input
    and output operations to make use of the pcio device driver.  If
    you use this interface you will only have to add a call to
    pcioInit() to open the connection to the pcio device, and change
    the include file to pcioDrv.h (from pcio.h).  All the rest of the
    code should remain unchanged.  The input and output routines make
    use of a global file descriptor initialize by pcioInit() in
    ioctl() calls to the driver.  To used this interface to the driver
    pcioDrv.o must be linked into the application and pcioDrv.h must
    be included wherever the driver is accessed.

    Modification history:

    7-Mar-1995  Fred Proctor removed // comment from this C header
    file.
    29-Dec-1994  Fred Proctor added DOS look-alikes
    ??? Steve Legowik created
