Loop library

Loopess is a small signal and select loop library for applications running on POSIX operating systems. It provides a convenient abstraction of signals, file descriptor events, and timeouts for single-threaded applications using a simple C++ class structure. Loopess properly handles the race condition introduced by mixing signals with the select system call. It uses sigsetjmp and siglongjmp to jump out of signals that occur just prior to entering the select call. Otherwise, these signals would not be processed until the next file descriptor event. Jumping out of these signals safely prevents entering into the blocking select system call. As of Feb 29, 2004, development on this project has been discontinued as per the maintainer.
