Oops, s/uintptr_t/intptr_t/
And this is actually already defined for C, so we need to just provide
the templates.
template <typename _U>
static inline void __always_inline
EV_SET(struct kevent *_kevp, uintptr_t _ident, uint32_t _filter,
uint32_t _flags, uint32_t _fflags, int64_t _data,
_U _udata)
{
EV_SET_(_kevp, _ident, _filter, _flags, _fflags, _data,
static_cast<intptr_t>(_udata));
}
/* specialize for std::nullptr_t */
template <>
inline void __always_inline
EV_SET(struct kevent *_kevp, uintptr_t _ident, uint32_t _filter,
uint32_t _flags, uint32_t _fflags, int64_t _data,
decltype(nullptr) _udata __unused)
{
EV_SET_(_kevp, _ident, _filter, _flags, _fflags, _data, 0);
}
