Hi Ed,
    Hmm, the program seems to be running fine here.  This is the output:

number of data in dataset: 1
number of data in dataset: 1
the float: 99.900002
number of data in dataset: 2
number of data in dataset: 2
the float: 88.800003

    What machine are you running on?  What version of HDF5?

Howdy all!

Seems like an error in the docs. The ref manual sez: (note last parameter)


Name: H5Gget_objname_by_idx
Signature:
    ssize_t H5Gget_objname_by_idx(hid_t loc_id, hsize_t idx, char
*name, size_t* size ) 


But, H5Gpublic.h contains the following:

H5_DLL ssize_t H5Gget_objname_by_idx(hid_t loc_id, hsize_t idx, char* name, 
size_t size);


The last parameter is not a pointer after all!
