This file discusses the PARxCH function library for all OS platforms.
This library is at the core of the software supplied with the board.
It has the functions that initialize and control board operation.

A typical sequence of calls to the library functions would be:

        ParXchOpen
        ParXchInit
        ParXchStart
        while (!done) {
                if (ParXchIsReady) {
                        ParXchGetData
                        process or save data
                        }
                }
        ParXchStop
        ParXchClose

The arguments for these functions are listed in the header file,
parxch.h.  For a complete example, see the source code for sample.c
in the example directory.

When using the library include the header file parxch.h in any source
code and include the library on the link command line.  This is
referred to as static linking and is available for all OS platforms.

Under Windows, the library can also be linked dynamically.  To do
this, include the import library, parxch.lib, on the link line.  This
provides the information for resolving references to the library
functions that are located in the Dynamic Link Library, parxch.dll.
Be sure to include the location of this DLL on your path environment
variable so the system can find it at run time.  For example:

        set path=%path%;\sr\parxch\lib

Under Linux, the library can also be linked dynamically by using the
shared library, libxch.so.  To do this, include -lxch on the link
line.  Be sure to include the location of the shared library on your
library search path so the system can find it at run time.  For
example:

  LD_LIBRARY_PATH=/usr/local/sr/parxch/lib:$LD_LIBRARY_PATH ; \
                                                     export LD_LIBRARY_PATH


For both WinNT and Linux, the function library is just a thin wrapper
around a kernel mode driver that does the actual work of
communicating with the A/D board.  Before the library will work, you
must first install the kernel mode driver.  See the readme.txt file
in the driver subdirectory for more information on how to install the
driver.
