psocksxx is a C++ wrapper for POSIX sockets (development files)
psocksxx library attempts to borrow the concepts from socket++ and socket-library, but not the code, and create a well documented (and hopefully easy to understand) POSIX socket communication wrapper in C++. To keep the code simple and clean this project will only support POSIX sockets. This package holds the development files.
