This contains a set of C test cases from UserGuideCode.
(modified for use with V3.3)

If CGNS is compiled with --enable-64bit, then the created "grid_c.cgns"
file will use 64-bit integers as appropriate

Currently, the testing (make test) only compares output files of some
of the variables written to and read from the grid_c.cgns file.  It
does not check whether the 64-bit integers were necessarily written
as I8 or not.  To check this, one could use "cgnsview" to look at the
grid_c.cgns file(s) directly.  For example, with 64-bit integers, in
the cgns file under Test_Grid_Str, the PointList data type under
the BC_t nodes (under ZoneBC_t) should be I8 rather than I4.

***** NOTE *****
You will first have to edit the Makefile include to set up your
CGNS location and compiler and options

Edit 'make.defs' for Linux/Unix
Not checked for Windows yet.

To just build the code, use
    make
on linux/Unix

To build and run the tests, use
    make test

Note: executables, output files, and the resulting CGNS file are put in
each Subdirectory/build/ directory

To clean everything up, use
    make clean
