inet6_rth_getaddr(3) — Subroutines
NAME
inet6_rth_getaddr − Retrieve an address for an index from an IPv6 Routing header
SYNOPSIS
#include <netinet/ip6.h>
struct in6_addr ∗inet6_rth_getaddr(
const void ∗bp,
int index );
LIBRARY
Standard C Library (libc)
PARAMETERS
bpPoints to a buffer that contains an IPv6 Routing header.
index
Specifies a value that identifies a position in a Routing header for a specific address. Valid values range from 0 to the return value from inet6_rth_segments() minus 1.
DESCRIPTION
The inet6_rth_getaddr() function uses a specified index value and retrieves a pointer to an address in a Routing header specified by bp. Call inet6_rth_segments() before calling this function in order to determine the number of segments (addresses) in the Routing header.
RETURN VALUES
Upon successful completion, the inet6_rth_getaddr() function returns a pointer to an address. Upon failure, it returns a NULL pointer.
