H A D | cdefs.h | diff 17648 Sun Aug 18 14:14:03 MDT 1996 peter Add __unused to the list of __dead, __dead2, __pure, __pure2 etc. gcc-2.7 has __attribute__((unused)) as a postfix operator on function arguments to prevent -Wunused from complaining about them. gcc < 2.7 doesn't have anything like this (and doesn't care about it either). eg: int foo(bar, baz) int bar __unused; /* needed because of function pointer typing */ char *baz __unused; { return (1); } |
