However, as long as you dedicate one thread to signal handling and block signals in all the other threads -(see <a href="https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_sigmask.html">pthread_sigmask()</a>) +(see <a href="https://pubs.opengroup.org/onlinepubs/9799919799/functions/pthread_sigmask.html">pthread_sigmask()</a>) then you should be able to use the selfpipe in the thread that handles signals without trouble. Since reading the selfpipe involves waiting for a file descriptor to become readable, it is recommended to do this in a thread that will already have a regular input/output loop (via -<a href="https://pubs.opengroup.org/onlinepubs/9699919799/functions/poll.html">poll()</a> +<a href="https://pubs.opengroup.org/onlinepubs/9799919799/functions/poll.html">poll()</a> or <a href="iopause.html">iopause()</a>) so you can just add the selfpipe to the list of fds you're reading on. </li> <li> In rare cases, the self-pipe can theoretically be filled, if some |
