Subject: [9fans] varargs question
Topicbox-Message-UUID: 4f1fb792-ead5-11e9-9d60-3106f5b1d025

as i was drifting off to sleep the other night,
i was wondering about varargs.  (clearly, it's
time for a vacation.)

and i wondered why kenc doesn't add an argument
count before the first vararg.  (bwc pointed out
that the address following the last vararg would be
more useful.)  va_* could be updated to deal with
the silent extra and abort on access beyond the end
of the actual variable arguments.  a function to check
that list == end could added for the paranoid.

since all code is prototyped these days,
is there any reason why this is a bad idea that i
haven't thought of?
