[Boost-users] Re: loop vs. for_each & boost::bind

Hi,

I have some code that runs fine:

for (Partition::iterator pi = renderRegions.begin(); pi != renderRegions.end(); ++pi); (*pi)->render(<t, foo, si);

I try to replace it by for_each & boost::bind,

std::for_each(renderRegions.begin(), renderRegions.end(), boost::bind(&Region::render, _1, <t, foo, si));

but si doesn't get modified, while it should be passed as reference.

Try using: std::for_each(renderRegions.begin(), renderRegions.end(), boost::bind(&Region::render, _1, <t, foo, boost::ref(si)));

-- With kind regards, Mathieu
