Well, I don't wanna be idiot, perhaps I am too tired, but n_long appears
in ip.h defined as :
beast# grep ipt_time /usr/include/netinet/ip.h
union ipt_timestamp {
n_long ipt_time[1];
n_long ipt_time;
} ipt_timestamp;
beast# grep ipt_time /usr/include/netinet/*
/usr/include/netinet/ip.h: union ipt_timestamp {
/usr/include/netinet/ip.h: n_long ipt_time[1];
/usr/include/netinet/ip.h: n_long ipt_time;
/usr/include/netinet/ip.h: } ipt_timestamp;
beast#
And, I simply don't find where ipt_time is defined ! I suppose it is
structure, perhaps it is of type ipt_timestamp, *g*.
And yes, those are all the files I include, nothing more, nothing less.
