? opendir() and readdir() are how this is done in C. They are not
insanely complex and there's a large amount of sample code that uses
those functions out there. Read some of that sample code and understand
it, then use the concepts you learn.

It is not clear what the OP wants. Maybe the OP should explain better.
The other thing that he could be thinking about is open()ing the
directory itself. This is not a good idea, because some programmers who
are more paranoid and dedicated than you have already written opendir()
and its friends, and Laziness is one of the virtues of a programmer.
Use dd(1) to read raw data from the disk and enjoy parsing binary
information, where you need the info in the *.h files. Or use ls(1),
find(1) and other shell commands.
dd is probably the wrong tool for the job as well, since it refuses to
dump data if you do "dd if=somedir/ ..." .
