AF_INET	src points to a struct in_addr (in network byte order) which is converted to an IPv4 network address in the dotted-decimal format, "ddd.ddd.ddd.ddd". The buffer dst must be at least INET_ADDRSTRLEN bytes long.
AF_INET6	src points to a struct in6_addr (in network byte order) 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.
EAFNOSUPPORT	af was not a valid address family.
ENOSPC	The converted address string would exceed the size given by size.

NAME

inet_ntop - convert IPv4 and IPv6 addresses from binary to text form

SYNOPSIS

bash

#include <arpa/inet.h>

bash

const char *inet_ntop(int \naf\n, const void *restrict \nsrc\n,\n
\n                      char \ndst\n[restrict .\nsize\n], socklen_t \nsize\n);

This function converts the network address structure src in the af address family into a character string. The resulting string is copied to the buffer pointed to by dst, which must be a non-null pointer. The caller specifies the number of bytes available in this buffer in the argument size.

inet_ntop() 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(). The following address families are currently supported:

AF_INET: src points to a struct in_addr (in network byte order) which is converted to an IPv4 network address in the dotted-decimal format, "ddd.ddd.ddd.ddd". The buffer dst must be at least INET_ADDRSTRLEN bytes long.
AF_INET6: src points to a struct in6_addr (in network byte order) 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.
