Re: [Boost-users] [bind] member function as signal handler

Hi, all!

I'd like to get a member function of an object to handle signals - is that possible with boost::bind? I tried the following, which doesn't work:

SomeClass{ ... bool done_;

public: void handler_done(int signal){ std::cout << "Recieved signal " << signal <<" ..." <

then, in the main: #include #include ... SomeClass someClass; signal( SIGINT,boost::bind( &SomeClass::handler_done, &someClass,_1) ); ...

I get the following error (g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3): error: cannot convert ‘boost::_bi::bind_t, boost::_bi::list2, boost::arg<1> > >’ to ‘void (*)(int)’ for argument ‘2’ to ‘void (* signal(int, void (*)(int)))(int)’

Is this generally impossible, or am I just making some stupid error from not really understanding boost::bind properly?

Thanks in advance!

That's not going to work, since signal expects a function pointer and not a function object. bind produces function objects. With Kind Regards, Ovanes
