For general C, try comp.lang.c. It's probably the wrong place
for these questions, since they are UNIX specific.

comp.unix.programmer (and perhaps comp.unix.questions) might
be the best place.

Check permissions: stat(2) is very general, but access(2) is easier
and probably adequate for your needs:

if (access("some/file", R_OK) == 0)
  printf("Readable\n");

Creating directories: mkdir(2)

If you intend to do more UNIX system programming in C, you should
try to get a decent book. I recommend Stevens: "Advanced Programming
in the UNIX Environment", Addison Wesley.

[And I really should get Debian book suggestions rolling soon...]
