ICMP(4P) ICMP(4P)
NAME
icmp - Internet Control Message Protocol
SYNOPSIS
#include <sys/socket.h>
#include <netinet/in.h>
s = socket(AF_INET, SOCK_RAW, proto);
DESCRIPTION
ICMP is the error and control message protocol used by IP and the Internet protocol family. It may be accessed through a "raw socket" for
network monitoring and diagnostic functions. The proto parameter to the socket call to create an ICMP socket is obtained from getprotoby-
name(3N). ICMP sockets are connectionless, and are normally used with the sendto and recvfrom calls, though the connect(2) call may also
be used to fix the destination for future packets (in which case the read(2) or recv(2) and write(2) or send(2) system calls may be used).
Outgoing packets automatically have an IP header prepended to them (based on the destination address). Incoming packets are received with
the IP header and options intact.
DIAGNOSTICS
A socket operation may fail with one of the following errors returned:
[EISCONN] when trying to establish a connection on a socket which already has one, or when trying to send a datagram with the destina-
tion address specified and the socket is already connected;
[ENOTCONN] when trying to send a datagram, but no destination address is specified, and the socket hasn't been connected;
[ENOBUFS] when the system runs out of memory for an internal data structure;
[EADDRNOTAVAIL]
when an attempt is made to create a socket with a network address for which no network interface exists.
