13 Jun 2011 So consider the following example program: #include About to raise SIGUSR1 After raising SIGUSR1 sigwait got signal: 30 About to unblock
4 Feb 2014 I will remove the sigaction() handler and try only sigwait(). . if (status[i] == 1) printf("thread %d: terminatedn",i+1); } // On linux this can be done
Two versions of sigwait() are available beginning with the Solaris Operating A of the previous example, and then issues sigwait() to handle the SIGINT signal.
The main thread spawns a number of threads and then calls sigwait with only for which is abnormal program termination (for example, SIGSEGV or SIGXFSZ). The Linux platform I run it on is Red Hat Advanced Server 2.1,
Compile with "-D_POSIX_PTHREAD_SEMANTICS" on Solaris, see sigwait(2) as to * why. * * (c) jp@devnull.cz */ #include <stdio.h> #include <sys/types.h>
When using sigwait to wait for SIGUSR1 or SIGUSR2, can you have it trigger a signal handler? The following code did NOT, and the example
EXAMPLE. See pthread_sigmask(3.
The sigwait() function selects a pending signal from set, atomically clears it from the system's set of pending signals, and returns that signal number in the
The sigwait() function selects a pending signal from set, clears it from the set of pending The <signal.h> file (see Header Files for UNIX-Type Functions) The following example suspends processing by using the sigwait() function and
A thread can wait for one or more signals to occur by calling sigwait. sigaction, for example) and a thread is waiting for the same signal in a call to sigwait, Linux implements threads as separate processes, sharing resources using clone(2).
