<NOTE_TO_APPLE>
Forgive me if this has been discussed, but the xcode-users list archive is
not searchable...FIX WEBSITE!
</NOTE_TO_APPLE>
I have lots of lazy initialization code...and unfortunately some code that
uses goto too. For example:
void foo(void* ptr)
{
require(ptr!NULL, ERROR);
OSStatus err = SomeToolboxCall(..);
...
ERROR:
...// note - err NOT used here
}
I've figured out that because the require() macro uses goto to jump around
the initialization of err. But Xcode/gcc makes this an error (NOT a
warning). The annoying fix for this is the following (which takes away from
the whole point of lazy initialization):
void foo(void* ptr)
{
OSStatus err = noErr;
require(ptr!NULL, ERROR);
err = SomeToolboxCall(..);
...
ERROR:
...// note - err NOT used here
}
I have too many of these cases to fix. My question, is that if this
shipping code works fine in CodeWarror - is there a way I can disable this
error in XC - or change it to a warning not an error?
Thanks!
