I'd like to use boost::function to wrap (pointer to) function to pass to template functions that expect function objects. I'm just wondering, though, if using boost::function wrapper will introduce additional overhead into the function call?
boost::function will introduce an extra virtual function call (which is not a big deal in most cases).
Actually it doesn't if I am not mistaken.
boost::function doesn't use virtual functions, but the effect is the same. boost::function adds one additional indirect call through a function pointer. Doug
