NAME

inet_ntop - Parse network address structures

SYNOPSIS

#include af, const void *src, char *dst, size_t cnt);

DESCRIPTION

This function converts the network address structure src in the af address family into a character string, which is copied to a character buffer dst, which is cnt bytes long.

inet_ntop(3) extends the __inet_ntoa__(3)? function to support multiple address families, inet_ntoa(3) is now considered to be deprecated in favor of inet_ntop(3). The following address families are currently supported:

AF_INET

src points to a struct in_addr (network byte order format) which is converted to an IPv4 network address in the dotted-quad format, ddd.ddd.ddd.ddddst must be at least INET_ADDRSTRLEN bytes long.

AF_INET6

src points to a struct in6_addr (network byte order format) which is converted to a representation of this address in the most appropriate IPv6 network address format for this address. The buffer dst must be at least INET6_ADDRSTRLEN bytes long.

RETURN VALUE

inet_ntop returns a non-null pointer to dst. NULL is returned if there was an error, with errno set to EAFNOSUPPORT if af was not set to a valid address family, or to ENOSPC if the converted address string would exceed the size of dst given by the cnt argument.

BUGS

AF_INET6 converts IPv6-mapped IPv4 addresses into an IPv6 format.
