NAME

ipsec initaddr - initialize an ip_address
ipsec addrtypeof - get address type of an ip_address
ipsec addrlenof - get length of address within an ip_address
ipsec addrbytesof - get copy of address within an ip_address
ipsec addrbytesptr - get pointer to address within an ip_address

SYNOPSIS

#include <freeswan.h>

const char *initaddr(const char *src, size_t srclen,
int af, ip_address *dst);
int addrtypeof(const ip_address *src);
size_t addrlenof(const ip_address *src);
size_t addrbytesof(const ip_address *src,
unsigned char *dst, size_t dstlen);
size_t addrbytesptr(const ip_address *src,
const unsigned char **dst);

DESCRIPTION

The <freeswan.h> library uses an internal type ip_address to contain one of the (currently two) types of IP address. These functions provide basic tools for creating and examining this type.

Initaddr initializes a variable *dst of type ip_address from an address (in network byte order, indicated by a pointer src and a length srclen) and an address family af (typically AF_INET or AF_INET6). The length must be consistent with the address family.

Addrtypeof returns the address type of an address, normally AF_INET or AF_INET6. (The <freeswan.h> header file arranges to include the necessary headers for these names to be known.)

Addrlenof returns the size (in bytes) of the address within an ip_address, 4(3), ipsec_rangetosubnet(3)

DIAGNOSTICS

Fatal errors in initsubnet are: unknown address family; unknown clash value; impossible mask bit count; non-zero host-number bits and clash is 'x'. Fatal errors in addrtosubnet are: unknown address family. Fatal errors in masktocount are: unknown address family; mask bits not contiguous.
