socket_send6(3) Library Functions Manual socket_send6(3) NAME socket_send6 - send a UDP datagram SYNTAX #include <libowfat/socket.h> ssize_t socket_send6(int s, const char* buf, size_t len, const char ip[16], uint16 port, uint32 scope_id); DESCRIPTION socket_send6 sends len bytes starting at buf in a UDP datagram over the socket s to UDP port port on IP address ip. You can call socket_send6 without calling socket_bind6. This has the ef- fect as first calling socket_bind6 with IP address :: and port 0. The meaning of scope_id is dependent on the implementation and IPv6 IP. On link-local IPv6 addresses it specifies the outgoing interface index. The name (e.g. "eth0") for a given interface index can be queried with getifname. scope_id should normally be set to 0. RETURN VALUE socket_send6 returns 0 if the datagram was sent successfully. If not, it returns -1 and sets errno appropriately. EXAMPLE #include <libowfat/socket.h> int s; char ip[16]; uint16 p; uint32 scope_id; s = socket_tcp4(); socket_bind6(s,ip,p); socket_send6(s,"hello, world",12,ip,p,scope_id); SEE ALSO socket_send4(3), socket_getifidx(3) socket_send6(3)
