## Detailed Description

A signalset it just a collection of signals. Many signal-related functions take signalsets for arguments. The signalset class makes signalsets easy to manage.

## Constructor & Destructor Documentation

## signalset()

signalset::signalset | ( |  | ) |

Creates an instance of the signalset class.

## ~signalset()

signalset::~signalset | ( |  | ) |

Deletes this instance of the signalset class.

## Member Function Documentation

## addAllSignals()

bool signalset::addAllSignals | ( |  | ) |

Add all signals to the set. Returns true on success and false on failure.

## addSignal()

bool signalset::addSignal | ( | int32_t | signum | ) |

Add the signal "signum" to the set. Returns true on success and false on failure.

## removeAllSignals()

bool signalset::removeAllSignals | ( |  | ) |

Remove all signals from the set. Returns true on success and false on failure.

## removeCrashSignals()

bool signalset::removeCrashSignals | ( |  | ) |

Remove signals from the set that the process class listens for in its handleCrash() method.

## removeShutDownSignals()

bool signalset::removeShutDownSignals | ( |  | ) |

Remove signals from the set that the process class listens for in its handleShutDown() method.

## removeSignal()

bool signalset::removeSignal | ( | int32_t | signum | ) |

Remove the signal "signum" from the set. Returns true on success and false on failure.

## signalIsInSet()

int32_t signalset::signalIsInSet | ( | int32_t | signum | ) | const

Returns 1 if the signal "signum" is in the set, 0 if it is not and -1 on error.
