This is what I use:
//
-----------------------------------------------------------------------------
// Reads a String dataset
//
-----------------------------------------------------------------------------
herr_t H5Lite::readStringDataset(hid_t loc_id, const std::string&
dsetName, std::string &data) {
hid_t did; // dataset id
hid_t tid; //type id
herr_t err = 0;
herr_t retErr = 0;
hsize_t size;
did = H5Dopen(loc_id, dsetName.c_str() );
if (did < 0) {
std::cout << "Error Opening Dataset" << std::endl;
return -1;
}
tid = H5Dget_type(did);
if ( tid >= 0 ) {
size = H5Dget_storage_size(did);
std::vector<char> buf(static_cast<int>(size+1), 0x00); //Allocate
and Zero the array
err = H5Dread(did, tid, H5S_ALL, H5S_ALL, H5P_DEFAULT,
&(buf.front()) );
if (err<0) {
std::cout << "Error Reading string dataset." << std::endl;
retErr = err;
} else {
data.append( &(buf.front()) ); //Append the string to the given
string
}
}
CloseH5D(did, err, retErr);
CloseH5T(tid, err, retErr);
return retErr;
}

I know these examples and they help me to understand the structures,

don't find string examples and (string) array examples. I have a
hdf5 file
(created with Matlab) and I would like to read in my C++ program. My
code:
std::vector<std::string> hdf::readStringVector( const std::string&
p_path )
const
{
H5::DataSet l_dataset = m_file.openDataSet( p_path.c_str() );
H5::DataSpace l_dataspace = l_dataset.getSpace();
hsize_t l_size[1];
l_dataspace.getSimpleExtentDims( l_size );
l_dataspace.close();
std::vector<std::string> l_vec( l_size[0] );
*** How can I read the array data
return l_vec;
