SIGPAUSE

sigpause − atomically release blocked signals and wait for interrupt

#include <signal.h>

int sigpause(int sigmask);

This interface is made obsolete by sigsuspend(2).

sigpause assigns sigmask to the set of masked signals and then waits for a signal to arrive; on return the set of masked signals is restored.

sigmask is usually 0 to indicate that no signals are to be blocked. sigpause always terminates by being interrupted, returning −1 with errno set to EINTR.

4.4BSD. The sigpause function call appeared in 4.3BSD and is deprecated.
