inet_ntop(3)inet_ntop(3)NAMEinet_ntop - Convert a numeric address to a text string
SYNOPSIS
#include <arpa/inet.h>
const char *inet_ntop(
int af,
const void *src,
char *dst,
size_t size );
LIBRARY
Standard C Library (libc)
PARAMETERS
Specifies the address family. Valid values are AF_INET for an Internet
Protocol Version 4 (IPv4) address and AF_INET6 for an IPv6 address.
Points to a buffer that contains the numeric Internet address. Points
to a buffer that is to contain the text string. Specifies the size of
the buffer pointed to by the dst parameter. For Internet Protocol Ver‐
sion 4 (IPv4) addresses, the minimum buffer size is 16 octets. For IPv6
addresses, the minimum buffer size is 46 octets. The <netinet/in.h
file defines the INET_ADDRSTRLEN and INET6_ADDRSTRLEN constants,
respectively, for for these values.
DESCRIPTION
The use of this routine is deprecated. Use the getnameinfo(3) routine
instead.
The inet_ntop() function converts a binary Internet address value to a
formatted text string.
RETURN VALUES
Upon successful conversion, the inet_ntop() function returns a pointer
to the buffer containing the text string. If the function fails, it
returns a NULL pointer.
ERRORS
If the inet_ntop() routine call fails, errno is set to one of the fol‐
lowing values: The address family specified in af parameter is invalid.
The size of the buffer is inadequate.
