This is a POSIX 2008 compliant library for C, it contains different kinds of data structures, features and functions. It's currently used for deduplicating common stuffs like log management, wrapper around Pthread's mutexes, conds, barriers, etc as it really painful that because I can't just call pthread_*_destroy and have it no-op if it isn't initialized yet.

There are nice data structures such as linked list, array list, queues, etc. Those data structures are abstracted too with interfaces. The interfaces also tries to have as much default implementation as possible to have fallback for an operation if it isn't explicitly implemented even if its not optimal.
