Member Function Documentation

alarm()

static uint32_t signalmanager::alarm ( uint32_t  seconds )

static

Sends signal SIGALRM to self after "seconds" have elapsed. If "seconds" is 0, the alarm is disabled. Calling this method cancels any previously set alarm.

Returns the number of seconds that were remaining until any previously scheduled alarm was to be delivered or 0 if there was no previously scheduled alarm.

getBlockedSignals()

static bool signalmanager::getBlockedSignals ( signalset *  sset )

static

Sets "sset" to the set of signals that were raised, but blocked during the most recent call to waitForSignals(). Returns true on success and false on failure.

ignoreSignals()

static bool signalmanager::ignoreSignals ( signalset *  sset )

static

Ignore signal "signum". Returns true on success and false on failure.

waitForSignals()

static bool signalmanager::waitForSignals ( signalset *  mask )

static

Wait until a signal NOT in the signal set "mask" has been received. Returns true on success and false on failure.
