OpenBSD 4.0 man 7 ip says:
struct sockaddr_in {
sa_family_t sin_family; /* address family: AF_INET */
u_int16_t sin_port; /* port in network byte order */
struct in_addr sin_addr; /* internet address */
};
/usr/include/netinet/in.h:
struct sockaddr_in {
u_int8_t sin_len;
sa_family_t sin_family;
in_port_t sin_port;
struct in_addr sin_addr;
int8_t sin_zero[8];
};
No wonder my program didn't work properly and sent UDP with a nonsensical
source port when I wrote it according to the manpage and the manpage is wrong.
When I added the sin_len entry, it started to work properly.
