Hey Tanzima,
1. I have an hdf5 file. Is it possible to iterate through the
different datasets and attributes etc.? If yes, how do I do that?
You can use H5Literate and H5Lvisit to iterate within a group in a flat
and recursive way respectively. Check out the Link reference page:
http://www.hdfgroup.org/HDF5/doc/RM/RM_H5L.html#Link-Iterate
Within the callback you specify you can check for the type of the link
in the info struct which will help you to decide what to do.
I also found that the example code is a fantastic source of information
about how things can be used. Below is a link to the sample C code for
HDF5 version 1.8:
http://www.hdfgroup.org/ftp/HDF5/examples/examples-by-api/api18-c.html
2. How do I extract the names of the datasets from this file to begin
with? I know how to extract info of a dataset once its name is given.
If you're not iterating/visiting through the file then you'll have to
know explicitly what to query. The iterator functions supply a name to
the callback, so you can use that. Alternatively, if you have an object
id (dataset/group/...) you can use the H5Iget_name(...) function to
return the name.

I hope this has helped.
Richard.
