cbase is a C library of useful functions that simplify systems software development on System V UNIX. The library includes routines for memory management, string parsing, filesystem traversal, subprocess execution, I/O, as well as implementations of common data structures such as linked lists, hash tables, stacks, and queues. The library also includes a high- level interface to Berkeley sockets, and an implementation of a scheduler which has functionality very similar to that of the cron daemon. Note: cbase was formerly known as CFL.
