Hi!
Does anyone know why NetBSD has udata defined as intptr_t in kqueue(3)?
I.e.:
EV_SET(&kev, ident, filter, flags, fflags, data, udata);
where the values are defined as:
struct kevent {
uintptr_t ident; /* identifier for this event */
uint32_t filter; /* filter for event */
uint32_t flags; /* action flags for kqueue */
uint32_t fflags; /* filter flag value */
int64_t data; /* filter data value */
intptr_t udata; /* opaque user data identifier */
};
while other operating systems have udata as "void *" instead?
This currently causes a bug report in wxWidgets.
OpenBSD:
https://man.openbsd.org/kevent
FreeBSD:
https://www.freebsd.org/cgi/man.cgi?kqueue
Mac OS too, but I can't find a public link to a man page for that.
