Subject: lxc/tools/lxc_monitor: include missing <stddef.h>
X-Git-Tag: lxc-3.1.0~325^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=77d407537f57c3fb92787bdda1eeaec7941d344f;p=thirdparty%2Flxc.git

lxc/tools/lxc_monitor: include missing <stddef.h>

lxc_monitor.c uses offsetof(), so it should include
<stddef.h>. Otherwise the build fails with the musl C library:

tools/lxc_monitor.c: In function ‘lxc_abstract_unix_connect’:
tools/lxc_monitor.c:324:9: warning: implicit declaration of function ‘offsetof’ [-Wimplicit-function-declaration]
         offsetof(struct sockaddr_un, sun_path) + len + 1);
         ^~~~~~~~
tools/lxc_monitor.c:324:18: error: expected expression before ‘struct’
         offsetof(struct sockaddr_un, sun_path) + len + 1);
                  ^~~~~~
