C++ Motor contorls

So this is a really simple question. How do you control the value of the victors and jaguars in C++? I can't seem to find any documentation of the functions so I'm a little confused. I would think it would be something like:

myvictor.set();........ or
myjag.set();.....

I'm pretty familiar with C++, I'm just not sure what functions are already created for these and what arguments need to be passed. Thanks for the help.
