Cannot figure out how to properly use lambda library in following situation (pseudo-code below): class Unit { }; class Test { public: void dosmth(Unit* unit) {} }; int main() { vector lst; Test t; for_each (lst.begin(), lst.end(), ?// I want to call t.dosmth with each Unit* in list } Any help will be greatly appreciated.

Cannot figure out how to properly use lambda library in following situation (pseudo-code below):

class Unit { };

class Test { public: void dosmth(Unit* unit) {} };

int main() { vector lst; Test t; for_each (lst.begin(), lst.end(), ?// I want to call t.dosmth with each Unit* in list }

Any help will be greatly appreciated.

Hi, you can take a look at the documentation Lambda expressions in details > Member functions as targets Best, Vicente

Thank you Vicente, I already did and in spite of existence of the docs I had to ask for a help. All options that I came up with failed to compile. I can post them here, but I thought that for the person who knows Lambda library the answer should be trivial.

for_each(lst.begin(), lst.end(), boost::lambda::bind(&Test::dosmth, boost::ref(t), boost::lambda::_1)); HTH, Boris
