Hi Todd,
Have you tried getting the ArrayType using CompType::getMemberArrayType, then ArrayType::getArrayDims?

A portion of my DataType is listed below. In my H5T_COMPOUND, I have a H5T_ARRAY called iq_data. How in my code can I get the number of elements in this array? From file to file, this array can vary in size and not always be 1000 elements. I am trying to figure out how to do this in C++ preferably but C is fine as well. I can obviously get the DataType object easily in C++, but don't know how to read information from this object. HDF5 "hdfFile.be01" { GROUP "/" { DATATYPE "DRdata" H5T_COMPOUND { H5T_ARRAY { [5] H5T_STD_U32LE } "guid"; H5T_STD_I32LE "version"; ... H5T_STD_U32LE "num_samps"; ... H5T_STD_U32LE "sequence_dummy"; H5T_ARRAY { [1000] H5T_COMPOUND { H5T_IEEE_F32LE "f_i"; H5T_IEEE_F32LE "f_q"; } } "iq_data"; } Thanks! Todd Dobmeyer
