SYNOPSIS

     except that c must be a lower-case letter.

     corresponding upper-case letter is returned if there is one; otherwise
     the argument is returned unchanged.  If the argument to the _toupper()
     function is a lower-case letter, the corresponding upper-case letter is
     returned; otherwise the output is undefined.
