Well, the underlying functions are in C. First of all it's much easier to deal with zlib that way
since it's in C. Plus good old void * for masking the data type in function calls (still getting
used to having to write a fortran function for each possible type and rank (ugh)). If you're
interested, my library is on the FEX. with fseek/etc, I can move all around the file (at the cost
performance depending on how wild you do stuff). Generally though it seems to be quick. It even
has partial I/O (hyperslabs in HDF) so I can read all/part/some/stride through datasets. So if you
have an enourmous matrix, you could read in part of that at a time. I have not optimized the
partial I/O by any means though. The C library although not done, is fairly complete. I'm trying
to write a fortran wrapper to that library.
