Libc-X provides extensions to the standard C library implementing useful and powerful data structures and functions. Its Unix name is libcx. It is not a template layer. It is made entirely with the C standard language, compatible with C++, and portable. All developed structures are designed to be used in stand-alone mode with limited dependencies with other features of Libc-X. For example, you can easily extract the header and the .c source of Hashtable and use it outside Libc-X.
