inet_ntop(3) Library Functions Manual inet_ntop(3)
NAME
inet_ntop - Converts a numeric address to a text string
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <arpa/inet.h>
const char *inet_ntop ( int af, const void *src, char *dst, size_t size) ;
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 Version 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 following values: The address family specified in af parameter is
invalid. The size of the buffer is inadequate.
