|
* Purpose: This program is run to generate an HDF5 data file with both
|
|
* empty and compact groups.
|
|
*
|
|
* To test compatibility between v1.6 and v1.7, compile and run
|
|
* this program, it will generate a file called "group_new.h5".
|
|
* You need to move it to the test directory in the HDF5 v1.6
|
|
* source tree. The test/stab.c program will read it.
