+.SH NAME
+inet_ntop \- convert IPv4 and IPv6 addresses from binary to text form
+.SH LIBRARY
+Standard C library
+.RI ( libc ", " \-lc )
+.SH SYNOPSIS
+.nf
+.B #include <arpa/inet.h>
+.PP
+.BI "const char *inet_ntop(int " af ", const void *restrict " src ,
+.BI "                      char " dst "[restrict ." size "], socklen_t " size );
+.fi
+.SH DESCRIPTION
+This function converts the network address structure
+.I src
+in the
+.I af
+address family into a character string.
+The resulting string is copied to the buffer pointed to by
+.IR dst ,
+which must be a non-null pointer.
+The caller specifies the number of bytes available in this buffer in
+the argument
+.IR size .
+.PP
+.BR inet_ntop ()
+extends the
+.BR inet_ntoa (3)
+function to support multiple address families,
+.BR inet_ntoa (3)
+is now considered to be deprecated in favor of
+.BR inet_ntop ().
+The following address families are currently supported:
+.TP
+.B AF_INET
+.I src
+points to a
+.I struct in_addr
+(in network byte order)
+which is converted to an IPv4 network address in
+the dotted-decimal format, "\fIddd.ddd.ddd.ddd\fP".
+The buffer
+.I dst
+must be at least
+.B INET_ADDRSTRLEN
+bytes long.
+.TP
+.B AF_INET6
+.I src
+points to a
+.I 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
+.I dst
+must be at least
+.B INET6_ADDRSTRLEN
+bytes long.
+.SH RETURN VALUE
+On success,
+.BR inet_ntop ()
+returns a non-null pointer to
+.IR dst .
+NULL is returned if there was an error, with
+.I errno
+set to indicate the error.
+.SH ERRORS
+.TP
+.B EAFNOSUPPORT
+.I af
+was not a valid address family.
+.TP
+.B ENOSPC
+The converted address string would exceed the size given by
+.IR size .

+POSIX.1-2001.
+.PP
+Note that RFC\ 2553 defines a prototype where the last argument
+.I size
+is of type
+.IR size_t .
+Many systems follow RFC\ 2553.
+glibc 2.0 and 2.1 have
+.IR size_t ,
+but 2.2 and later have
+.IR socklen_t .
+.\" 2.1.3: size_t, 2.1.91: socklen_t
+.SH BUGS
+.B AF_INET6
+converts IPv4-mapped IPv6 addresses into an IPv6 format.
