|
* Purpose: This program is run to generate a HDF5 data file with fill
|
|
* value property. A new fill value design has been put into
|
|
* library v1.5. To test compatibility between v1.4 and v1.5,
|
|
* compile and run this program, it will generate a file called
|
|
* fill_new.h5. You need to move it to the /test directory
|
|
* in HDF5 v1.4 source codes. The fillval.c program will read it.
