/* The compiler often warns you if you give a function formal parameter a
|
|
name, but don't use it. But because assert() disappears when doing an
|
|
optimized build, the compiler doesn't recognize your reference to the
|
|
parameter in the assert() argument. To avoid the bogus warning in
|
|
this case, we have ASSERT_ONLY_ARG(), which declares a name for a
|
|
formal parameter for purposes of assert() only. In cases where an
|
|
assert() would disappear, ASSERT_ONLY_ARG() disappears too.
|
|
|
|
E.g.
|
|
|
|
void foo(int const ASSERT_ONLY_ARG(arg1)) {
|
|
|
|
assert(arg1 > 0);
|
|
}
