C help recommendations?

[Luyseyal <luyseyal austin cc tx us>]

i've forgotten so much of my C since school, it's not even funny.
could someone recommend an online instructional text? dead trees
don't do anything for me: no copy/paste. :-)

i've already read the comp.os.c-FAQ and i have bookmarks to the
glibc manual and gtk+ tutorial. but i need refreshing on such
boring topics as static and virtual functions and other such useful
nonsense.:-)

extreme amounts of thanks,
