The documentation pages in the reference manual for H5Z filter API is referring to an external page with an embedded PDF when talking about “HDF5 Dynamically Loaded Filters”. Can this document be converted into an actual doxygen documentation? It is as important as the H5Z* functions themselves and deserves the same level of accessibility.
Btw., it looks strange that herr_t H5Zregister() takes a void* as argument, but then the documentation specifies the argument needs to be an argument to the H5Z_class*_t structures. Wouldn’t HDF5 benefit from more type-safety in its API?
