help with sendto (linux)

I've been having trouble with sendto function (I open a socket, bind it to
eth0, recvfrom works fine but when I execute following line I get sendto():
invalid argument)

if(sendto(sokit, buf, sizeof(buf), 0, (struct sockaddr *)&drugaadr,
sizeof(drugaadr))==-1){
perror("sendto()")
exit(-1)
}

sokit is int variable with socket handler (value 3)
buf is declared char[60]
drugaadr is struct sockaddr_in

drugaadr.sin_family=AF_INET;
drugaadr.sin_port=0;
drugaadr.sin_addr.s_addr=inet_addr("192.168.0.1");
and the drugaadr.sin_zero is filled with 8 zeros.

Please help (I'm trying to send an ARP packet, but that's within buf, and it
shouldn't have anything to do with sendto failure), I've searched the
internet but came empty-handed.

Thanks,

Vedran

Then you want to ask your question on comp.unix.programmer. Only
ANSI/ISO C, which does not include sendto() or any other network
functions, is discussed here.

This is not a standard C function. You need to find a newsgroups where
it is on-topic. There are a number of Linux groups, one is surely right.
If it's a POSIX function (I'm not sure) then comp.unix.programmer might
be suitable.

Wrong door. You want comp.unix.programming or somesuch, sockets and
networking are offtopic here, but topical there.

Thanks, that's what I'll do.
