Well, yes, but the problem is how a function can get the name of the
function which is calling it so that you can print it in the first
place.

To go back to the original question, why not modify the function
slightly so that it takes an addtional char* argument and pass the name
of the caller when it calls the function?  Seems like the least work to
do what Fred's friend wants, unless there are dozens or hundreds of
instances of the function in question being called.
