I'd suggest this:
#define EV_SET(kevpin, a, b, c, d, e, f) do { \
struct kevent *kevp = kevpin; \
(kevp)->ident = (a); \
(kevp)->filter = (b); \
(kevp)->flags = (c); \
(kevp)->fflags = (d); \
(kevp)->data = (e); \
(kevp)->udata = (f); \
} while(0)
As opposed to what it is currently defined as:
#define EV_SET(kevp, a, b, c, d, e, f) do { \
(kevp)->ident = (a); \
(kevp)->filter = (b); \
(kevp)->flags = (c); \
(kevp)->fflags = (d); \
(kevp)->data = (e); \
(kevp)->udata = (f); \
} while(0)
The alternative I'm suggesting will work in the use case:
EV_SET(&kev_in[numchanges++], fd, EVFILT_READ, EV_DELETE, 0, 0, 0);
Which is probably a common way to try to use the macro, and the existing
behavior can certainly catch you off guard...
