Re: [Boost-users] A question about boost::bind function

void AddUserAge( int& age ) { ++age; }

int _tmain(int argc, _TCHAR* argv[]) { std::vector<_sUserData> vUserData; for( int i = 0; i < 10; ++i ) vUserData.push_back( _sUserData() ); std::for_each( vUserData.begin(), vUserData.end(), boost::bind( AddUserAge, boost::bind( &_sUserData::m_nUserAge, _1 ) ) ); return 0; }

This compiles in 1.33, but doesn't actually increment the age; the inner bind returns a temporary int by value, and the outer bind increments that. Can you please try boost::bind( &_sUserData::m_nUserAge, _1 ) and see if it helps?
