8^) there in the library.
Answer:
#include <sys/types.h>
Anything ending in "_t" is most likely a type (i.e. offset type).
In the future, if something is undefined, but it's not your fault
(er...um...), try doing something like this:
% grep off_t /usr/include/*.h
% grep off_t /usr/include/sys/*.h
That'll get it most of the time.
TIP: If it's a declaration, you might even want to "| grep typedef"
to narrow the output down to the necessities.
As for the books and $, all the resources you need are sitting in
/usr -- man pages, header files, and libs (use nm) are typically
enough to figure out the tricks!
