Signal blocking under Linux & OS X
Project description
Provides access to sigprocmask(2) and friends and convenience wrappers to python application developers wanting to SIG_BLOCK and SIG_UNBLOCK signals in critical sections of their code.
Most common usage
from signal import SIGINT, SIGTERM from pysigset import suspended_signals with suspended_signals(SIGINT, SIGTERM): # Signals are blocked here.. pass # Any pending signal is fired now..
Also available
sigaddset(*args) int sigaddset(sigset_t *set, int signum) sigdelset(*args) int sigdelset(sigset_t *set, int signum) sigemptyset(*args) int sigemptyset(sigset_t *set) sigfillset(*args) int sigfillset(sigset_t *set) sigismember(*args) int sigismember(const sigset_t *set, int signum) sigpending(*args) int sigpending(sigset_t *set) sigprocmask(*args) int sigprocmask(int how, const sigset_t *set, sigset_t *oldset) sigsuspend(*args) int sigsuspend(const sigset_t *mask)
Similar tools
python-signalfd provides access to sigprocmask and signalfd. Its advantage is access to signalfd. Its disadvantage is a compilation requirement.
pysigset has a pythonic interface and requires only ctypes access to libc.so.6 or libSystem.B.dylib.
