| |
just to stir the pot a bit regarding the discussion of the two different ways to define macros, i've just noticed that the "({ })" notation is not universally acceptable. i've seen examples where using that notation causes gcc to produce:
error: braced-group within expression allowed only inside a function
i wasn't aware that there were limits on this notation. can someone clarify this? under what circumstances *can't* you use that notation? thanks.
