HDF5 C++: read a string in a compound data set

Question

Hello everyone nowadays I am working on how to read HDF compound dataset. My question is how can I get the name of the compound dataset members, I tried to get but it gave me empty name. However, when I try to get the name of members in Linux I got it but in windows MVS 2010 I could not. Any help would be appreciated.

What I have tried:

C++

H5T_class_t cTT = dataSet.getTypeClass();

if( cTT == H5T_COMPOUND )
{
      H5::CompType dc = dataSet.getCompType();

      for( int i = 0; i < dc.getNmembers(); i++ )
      {
           H5std_string memberName = dc.getMemberName( i );
          
          //memberName is = NULL; in windows
          //memberName is = ok; in linux     
      }
}

What do you mean by "memberName is = NULL; in windows"?

I don't know HDF but a quick research shows that H5std_string seems to be a std::string. That can't be NULL (but an empty string).
To access the string use memberName.c_str() and convert the encoding if necessary (it is probably UTF-8 which must be then converted before printed with Windows builds).

If you Google a bit you might have found the documentation of H5::StrType. With the function getCset() you should get a char* to work with.

Check your compiler settings that you are working with UNICODE. Read this link to enable Support for Unicode in Visual Studio.
