Hi,
I'm familiarizing myself with the HDF5 C++ interface. I'm having trouble understanding why H5Location::getObjType() takes a void* reference to an object when I would expect it to refer to "this". Same holds for get/setComment(), etc. Seems they should be static methods if we're passing in the object pointer. What am I missing?
Also, when I specify a name (char*) to a method like H5Location::reference(), is it understood that it is a relative path from the current group (i.e., "this", assuming it is a group)? What if the name starts with '/'?
I want to stay entirely in C++.

Hello Oscar,
"this" identifies the "dataset containing the object reference or the group containing that dataset." Please refer to the C function manual page for more details: https://www.hdfgroup.org/HDF5/doc/RM/RM_H5R.html#Reference-GetObjType1
The HDF5 C++ API is a simple wrapper of the C API, thus, the argument name should follow the same syntax as the name in the C API. Please refer to this page for information about names: https://www.hdfgroup.org/HDF5/doc/RM/RM_H5G.html
I hope this helps. Thanks,
Binh-Minh
