Changed H5Acreate2 -> H5Acreate_by_name, to be more consistent with
other new API routines.
Re-added simpler form of H5Acreate2, which creates attributes directly
on an object.
Tested on:
FreeBSD/32 6.2 (duty) in debug mode
FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode
Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe,
in debug mode
Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN,
in production mode
Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
in production mode
Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
w/szip filter, in production mode
Mac OS X/32 10.4.10 (amazon) in debug mode

|
*
|
|
* Purpose: Create a dataset with a null dataspace and an attribute
|
|
* with a null dataspace.
|
|
* This program is used to create the test file `tnullspace.h5' which
|
|
* has dataspaces stored in the newer (version 2) style in the object headers.
|
|
* To build the test file, this program MUST be compiled and linked with
|
|
* the hdf5-1.7+ series of libraries and the generated test file must be
|
|
* put into the 'test' directory in the 1.6.x branch of the library.
