A set of classes used to simplify error handling with POSIX and UNIX functions in C++ programs. Header and `.cpp` files. Contains a class that works with `errno` errors, and one that works with `getaddrinfo` errors.

A few small macros used to simplify error handling in C++ code that uses POSIX and UNIX system calls. Depends on an exception class UNIXError, which just happens to have an argument-less constructor that will get an error string based on the current value
#define ERR(__statment, __retVar) ((__retVar=(__statment))==-1 ? throw UNIXError() : (__retVar))
#define ERR_ERRVAL(__statment, __retVar, __errval) (((__retVar)=(__statment))==(__errval) ? throw UNIXError() : (__retVar))
