WebIf more than one thread is using sigwait() to wait for the same signal, no more than one of these threads will return from sigwait() with the signal number. If more than a single thread is blocked in sigwait () for a signal when that signal is generated for the process, it is unspecified which of the waiting threads returns from sigwait (). WebIf more than one thread is using a sigwait function to wait for the same signal, only one of these threads will return from the sigwait function with the signal number. If more than one thread is waiting for the same signal, the first thread to wait on the signal will return from the sigwait function. Authorities and Locks. None. Parameters *set
WebC library/kernel differences The original Linux system call was named sigpending(). However, with the addition of real-time signals in Linux 2.2, the fixed- size, 32-bit sigset_t argument supported by that system call was no longer fit for purpose.
