Hello,
In C, it's common to have various values that you combine via '|'. In most of
the C interfacing vocabs that I've used, these values are provided via a
simple word definition. So the question is, how do you OR them together?
There are a few ways to go about it. After trying out a few, I finally
settled on a macro named 'flags'. For now, it's tucked away in the obscure
vocab 'unix.linux.ifreq'. If it becomes generally used, I'll put it in a
better place. It's very simple to use:
{ S_IRUSE S_IWUSR S_IXUSR } flags
I like that better than:
S_IRUSE S_IWUSR bitor S_IXUSR bitor
Another benefit is that the values are combined at compile time.
