How can I easily replace characters in a std::string with another character?

Basically what I'd like is something like gsub (an addition to the string class in GNU's C++ class library). But I'm stuck on the Windows platform, and strongly encouraged to use the standard libraries as far as possible.

First I tried using string::iterator and indexing, but got terribly long errors when doing that.

Now my working solution is something like

Convert it to a C-string (string::copy)
Iterate over C-string, replacing characters
Stick the C-string back into the C++-string

Is there an easier way?
