c source code utilities wanted

[The Joker]

	- SOURCE? - SOURCE? - SOURCE? - SOURCE? - SOURCE? - SOURCE? -

could  someone send me  complete portable c  source code  modules  to utilities
such  as linked list routines  (b-trees, avl trees, add_node()/delete_node...),
perhaps a window package (something equivalent to OSSI, only in C, not Pascal),
interprocess  communication  routines,  terminal emulation,  perhaps  a  memory
manager? i just discovered the network news; lately i have  been  thinking that
i am spending  an  enormous  amount of time  writing code that  already exists.
portabile object-oriented code is preferred as much as possible.
if anyone would like to swap code, please let me know.
