Re: [Boost-users] boost function ==

Dear all,

We all waited for the operator==. Unfortunately it does not compile on VC++ 7.1. What do I wrong:

namespace Tstb { int f0 (); int f1 (int a); int f2 (int a, int b); int f3 (int a, int b, int c); }

void Test { boost::function fc1 = &Tstb::f0; boost::function fc2 = &Tstb::f0; boost::function fc3 = boost::bind(&Tstb::f1, 2);

bool b = false;

b = (fc1 == fc2); b = (fc1 == fc3); b = (fc2 == fc3); }

You've been mislead by the name. function::operator== is not an operator==. Here's how it's supposed to be used: boost::function fc1 = &Tstb::f0; boost::function fc3 = boost::bind(&Tstb::f1, 2); bool b = false; b = (fc1 == &Tstb::f0); b = (fc3 == &Tstb::f0); b = (fc1 == boost::bind(&Tstb::f1, 2)); b = (fc3 == boost::bind(&Tstb::f1, 2));

Wkr, me
