Section 63.5 noted that select() can't be used to wait on both signals and file descriptors, and described a solution using a signal handler and a pipe. A related problem exists when a program needs to wait for input on both a file descriptor and a System V message queue (since System V message queues don't use file descriptors). One solution is to fork a separate child process that copies each message from the queue to a pipe included among the file descriptors monitored by the parent. Write a program that uses this scheme with select() to monitor input from both the terminal and a message queue.
