Re: SIGALRM in a class member?
Ron Eggler wrote:
signal( SIGALRM, sendHeartbeat );
but the problem is signal wouldn't allow me to have a function pointer to a
member method like INITSource::sendHeartbeat. If I need to do it this way I
would end up in crazy static declarations and linker conflicts - I have
gone there already and apparently didn't solve it...
You can do this with a forwarding function that is a static member (you
can also do it with a non-member function). Because signal does not
give you a way to attach some caller defined data, you will also need a
static member variable to hold a pointer to the instance of the class
you want to use:
singleton = this;
static void sighandler_trampoline(int sig)
void sighandler(int sig)
// add your logic here
static foo *singleton;
foo *foo::singleton = 0;
