No, it can only return one value via the name of the
function.  To return multiple values you can pass a
pointer to a variable in the calling program and use
that pointer within the function to set its value.
For example, remD() returns a status via the name of
the function and the string removed via a pointer to
a char *.

Those are other possibilities that require more code.
