Re: WRAPPER FUNCTION
Please repair your keyboard, the capslock key seems to be stuck...
A wrapper function is a pretty broad term, generally means a function which calls another function to do the real work. The wrapper function itself might change the parameters a bit, do some error checking or something trivial like that.
There might be a more specific definition of "wrapper function" in a specific language or environment, but since you don't specify any it's hard to say anything more...
