Member Function Documentation

◆ graceful_quit()

sig_atomic_t ASSA::SIGINTHandler::graceful_quit ( )

inline

Indicates whether graceful quit signal has been raised by the signal handler.

Returns: 0 if not, 1 othewise.

Definition at line 92 of file Handlers.h.

{
    return m_graceful_quit;
}

References m_graceful_quit.

◆ handle_signal()

int ASSA::SIGINTHandler::handle_signal ( int signum_ )

inlinevirtual

Receive SIGINT signal.

Returns: 0 if valid signum_ was used, -1 otherwise.

Reimplemented from ASSA::EventHandler.

{
    trace_with_mask("SIGINTHandler::handle_signal", SIGHAND);
 
    if (signum_ == SIGINT) {
        m_graceful_quit = 1;
        return 0;
    }
    return -1;
}
