here is one of the example, maybe not the best. #include <vector> #include "boost/function.hpp" #include "boost/bind.hpp" void apply( boost::function f, int i) { f(i); } int main( ) { static boost::function my_function = 0; std::vector<int> v; std::for_each(v.begin(), v.end(), boost::bind(apply, my_function, _1)); }

In the code below my objective is pass a nullary function object to apply, and for that nullary function object to be 'my_function()' called with each member of the vector. How can I recode the call to apply as a unary bind expression such that I can write the for loop as a for_each loop?

Thx,

- Rob.

#include <vector> #include "boost/function.hpp" #include "boost/bind.hpp"

void apply( boost::function f ) { f( ); }

int main( ) { static boost::function my_function = 0;

std::vector<int> v;

for ( std::vector<int>::iterator i = v.begin( ); i != v.end( ); ++ i ) { apply( bind( my_function, * i ) ); } }
