DESCRIPTION sigsuspend() temporarily replaces the signal mask of the calling process with the mask given by mask and then suspends the process until delivery of a signal whose action is to invoke a signal handler or to terminate a process. sigsuspend linux

The sigsuspend() function shall replace the current signal mask of the calling thread with the set of signals pointed to by sigmask and then suspend the thread until delivery of a signal whose action is either to execute a signalcatching function or to terminate the process. This shall not cause any other signals that may have been pending on the process to become pending on the thread.

Apr 15, 2013  While this answer is a lot better than Arkku ones, it in general not correct to do the second sigprocmask after sigsuspend returned. The idea is to block SIGUSR1 before it can happen, then enter sigsuspend and wait for pending signals (signals that happened but which are blocked). sigsuspend also unblocks those signals so that when they happen(ed) a signal handler will be called before sigsuspend How can the answer be improved?sigsuspend linux C librarykernel differences The original Linux system call was named sigsuspend().

The original Linux system call was named sigsuspend(). However, with the addition of realtime signals in Linux 2. 2, the fixedsize, 32bit sigsett type supported by that system call was no longer fit for purpose. Consequently, a new system call, rtsigsuspend(), was added to support an enlarged sigsett type. sigsuspend linux
