valloric YCM [header definitions]

I'm looking for where the u_int, u_long headers are defined?

for instance MOD_LOAD, UNLOAD, ENOTSUP along with u_int and u_long aren't
being picked up by libclang

module_t isn't being found either but I located that header file in
/usr/include/sys/module.h

snd_modevent(module_t mod, int type, void *data)
{

switch (type) {
case MOD_LOAD:
break;
case MOD_UNLOAD:
break;
default:
return (ENOTSUP);
break;
}
return 0;
}

Anyone here uses YCM?

Here's a verbose output of my global ycm_config. I hard coded the values to
test but still some headers like u_int, u_long and the above mentioned
MOD_* aren't being picked up.

Any ideas why?
