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. |
