| I've got some code that calls GetKeys( KeyMap theKeys ) to get the modifier keys state. Then I use a mask to test which of them are down. I get a compile error:
error: no match for 'operator&' in 'theKeys[1] & 2l'
First, I know that I need to find constants for the key masks, what are those masks? But now that KeyMap is an array of BigEndianLong rather than UInt32, the compiler can't find an operator & that works with it. What is the best way to deal with this in our new Universal Binaries world?
Also, I have a SHORT that I want to set the most significant bit on. Currently the code is
result |= 0x8000;
What's the rule of thumb to make it cross chip happy?
Thanks.
