hi there,
i noticed freebsd has a few of the following macros:
#define FUNC(sb)
when you do something like
if (cond)
FUNC(i)
you missed an important part....
it's probably
if (cond)
FUNC(i);
(note the ';')
THAT would be ok....
without the ';' you just made whatever comes next conditional.
the compiler complains about an if statement with an empty body. any sensible
way of dealing with this issue?
i saw some reiserfs code which does the following to silence compilers:
#define FUNC(sb) do { } while (0)
yeah we do that too in some places.
(certainly at work I have done so)
cheers.
