[opensource-dev] I could use a little help with boost and callbacks and stuff

[Ricky]

Is something like:
std::bind1st(std::mem_fun(&MyClass::MyMethod), myParameter)
what you are looking for?

You can see working code using that on lines 350-390 of
https://bitbucket.org/kf6kjg/gsp-420-engine-design-graphics/src/120a2081bb2f/src/audio_core/AudioCore.cpp
(This was code I wrote while helping out another team in one of my classes.)

Boost's Bind function
(http://www.boost.org/doc/libs/1_47_0/libs/bind/bind.html) generalizes
the standard call I used, and so might be easier to use.  Here's the
same using Boost:
bind(&MyClass::MyMethod, myParameter)

I hope this helps,
Ricky
