[boost] Re: [format]: c_str() function

but that's the problem : a temporary is still required... ... Why not store std::string fconcat = str(f); and then use it rather than f, to simply and clearly decouples temporary / c-string aspects from the formatting action ?

I see. With this info c_str() seems rather pointless. I was hit by using "f.str().c_str()" and got corrupted data, that was main motivation. Thanks for answer, /Pavel
