Since all "labels" (symbols), if not ''local'', can be seen by the whole code in the same source unit, we don't need special care to let the subroutine <tt>func_f</tt> call <tt>func_m</tt>. If the function would have been in another source unit, we should have declared it <tt>extern</tt> (the linker will resolve the symbol), as done for <tt>printf</tt>.<br> |
