[Boost-users] boost::lambda question

OK, I'm a bit of a boost noob. I have a container of std::wstring's and I want to use a lambda expression in a for_each loop to pass each string to a WinAPI function - however, I need access to the c_str() method, and this is giving me a problem. For example, if I want to use the DeleteFile WinAPI call, I want to write something like: std::vectorstd::wstring v; ... for_each(v.begin(), v.end(), ::DeleteFile(_1)); But the above won't work as I need to pass the 'C' string to ::DeleteFile. So, I really want to be able to do something like this: for_each(v.begin(), v.end(), ::DeleteFile(_1.c_str())); Any ideas how I can access a member function (like c_str()) using a lambda placeholder?
