* Purpose: This test creates a file and a bunch of objects in the
|
|
* file and then calls MPI_Finalize without closing anything. The
|
|
* library should exercise the attribute callback destroy attached to
|
|
* MPI_COMM_SELF and terminate the HDF5 library closing all open
|
|
* objects. The t_prestart test will read back the file and make sure
|
|
* all created objects are there.
