[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 <<" ..." <<std::endl;
done_ = true;
}
};

then, in the main:
#include <signal.h>
#include <boost/bind.hpp>
...
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<void, boost::_mfi::mf1<void, 
SomeClass, int>, boost::_bi::list2<boost::_bi::value<SomeClass*>, 
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!

Tim
