go - Find the path to the executable

Question

I compile a program with Go for various platforms and run it by calling a relative path or just by its name (if it is in the PATH variable).

Is it possible to find out where the executable is?

Say, my program is called "foo(.exe)". I can run ./foo, foo (if it's in the PATH), ../../subdir/subdir/foo.

I have tried to use os.Args[0] and I guess I should check if the program name contains something different besides "foo". If yes, use filepath.Abs, if no, use (I can't find the function name, there is a function that looks through the PATH to check where the program is).
