Re: [Boost-users] Testing a boost::signal

if (!sig.empty()) doSomething(); But if you just want to "fire" your signal, you don't have to test its emptiness. 2008/7/13, Simon Pickles <sipickles@googlemail.com>:

Hi,

What is the correct syntax to test whether a signal has any slots connected?

boost::signal<void(void)> sig;

if (sig) DoSomething();

This doesn't compile.

Thanks
