Hello,
Here's my implementation of the two system calls. The patch is against HEAD
from a couple of days:
commit ff9e83788d7ed52342dcba4dff1e62fdf3cc985c
Author: ngie <n...@freebsd.org>
Date: Mon Jan 4 03:34:22 2016 +0000
Remove free'ing of an uninitialized variable
Just remove it completely from the test as it's initialized but unused
apart
from the free(3) call
Differential Revision: https://reviews.freebsd.org/D4769 (part of
larger diff)
MFC after: 5 days
Reported by: cppcheck
Reviewed by: oshogbo
Sponsored by: EMC / Isilon Storage Division
I've made brief tests using the examples in the manpages in Linux skipping
the timeout stuff:
http://man7.org/linux/man-pages/man2/sendmmsg.2.html
http://man7.org/linux/man-pages/man2/recvmmsg.2.html
I've tried to stick to the comments in the thread but any
suggestions/testings
are also welcomed so that I can fix the calls accordingly.
Regards,
Boris Astardzhiev
