GETIFADDRS(3) System Library Functions Manual GETIFADDRS(3)
NAME
getifaddrs - get interface addresses
SYNOPSIS
#include < sys/types.h>
#include < sys/socket.h>
#include < ifaddrs.h>
int
getifaddrs(struct ifaddrs **ifap);
void
freeifaddrs(struct ifaddrs *ifap);
DESCRIPTION
The getifaddrs() function stores a reference to a linked list of the net-
work interfaces on the local machine in the memory referenced by ifap.
The list consists of ifaddrs structures, as defined in the include file
< ifaddrs.h>. The ifaddrs structure contains at least the following
entries:
struct ifaddrs *ifa_next; /* Pointer to next struct */
char *ifa_name; /* Interface name */
u_int ifa_flags; /* Interface flags */
struct sockaddr *ifa_addr; /* Interface address */
struct sockaddr *ifa_netmask; /* Interface netmask */
struct sockaddr *ifa_broadaddr; /* Interface broadcast address */
struct sockaddr *ifa_dstaddr; /* P2P interface destination */
void *ifa_data; /* Address specific data */
ifa_next
Contains a pointer to the next structure on the list. This field
is set to NULL in last structure on the list.
ifa_name
Contains the interface name.
ifa_flags
Contains the interface flags, as set by ifconfig(8).
ifa_addr
References either the address of the interface or the link level
