Michael Kerrisk 821e74fad4 sendmmsg.2: Minor fix-ups for Elie De Brauwer's patch 
Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
 2012-12-17 20:15:01 +01:00
Elie De Brauwer daf3eb0c70 sendmmsg.2: Add example program for sendmmsg() 
The example uses sendmmsg() to send out a string "onetwo"
on a first datagram, where both halves originate from
distinct buffers and a second datagram contains "three",
coming from a single buffer.

Tested with netcat listening:
root@ubuntu:~# nc -l -u -p 1234
onetwothree

And tcpdump peeking:
root@ubuntu:~# tcpdump -c 2 -s 0 -X -ni lo tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lo, link-type EN10MB (Ethernet), capture size 65535 bytes

4 (SYSLOG_ACTION_READ_CLEAR).

Michael Kerrisk 27bada1fa1 getrlimit.2: Document Linux's nonstandard treatment or RLIMIT_CPU soft limit 
Upon encountering the RLIMIT_CPU soft limit when a SIGXCPU handler
has been installed, Linux invokes the signal handler *and* raises
the soft limit by one second. This behavior repeats until the
limit is encountered.  No other implementation that I tested
(Solaris 10, FreeBSD 9.0, OpenBSD 5.0) does this, and it seems
unlikely to be POSIX-conformant. The (Linux-specific)
RLIMIT_RTTIME soft limit exhibits similar behavior.
