Look at the functions in search.h (eg, tsearch(3)). C++98's std::set
tends to provide a set-like interface to a binary tree implementation,
so you could provide your own light interface wrapper around the POSIX
tree implementation.
My man page says the tree functions are SVID only; the hash map (eg,
hcreate(3)) functions are POSIX, though, and those could also be
adapted to provide set-like operations.
