Hi everyone,
I am wondering how to write a std::string as an attribute to an HDF5 group.
I have found code for C and Java, but not for C++. I tried massaging the
code i found, but it throws an exception and im all out of ideas.

Thanks,
Isaac

Hi Isaac,

Are you trying to use HDF5 C library in your C++ code or are you trying to
use the HDF5 C++ API?

We don't have such example yet, but you might find what you need in the C++
tests from our distribution: hdf5/c++/test/tvlstr.cpp, specific test is
test_vlstring_attribute.

Thanks. Here is a snippet of my code which appears to work....
//m_pConfig->getFilename() returns a std::string

H5File file(hdfFilename,H5F_ACC_TRUNC);
Group dataGroup = file.createGroup("/data");
StrType vlst(0, H5T_VARIABLE);
Attribute attrConfigFilename = dataGroup.createAttribute("configFilename",
vlst, DataSpace(H5S_SCALAR));
attrConfigFilename.write(vlst, m_pConfig->getFilename());
