.Dt LWRES_INETATON 3
.Os BIND9 9
.ds vT BIND9 Programmer's Manual
.Sh NAME
.Nm lwres_net_aton
.Nd lightweight resolver IPv4 address manipulation
.Sh SYNOPSIS
.Fd #include <lwres/int.h>
.Fd #include <lwres/net.h>
.Fd
.Ft int
.Fo lwres_net_aton
.Fa "const char *cp"
.Fa "struct in_addr *addr"
.Fc
.Sh DESCRIPTION
.Fn lwres_net_aton
checks that
.Fa cp
is a valid ASCII representation of an IPv4 address and optionally converts
it to a binary address in network byte order.
If
.Fa addr
is not
.Dv NULL,
.Li addr->s_addr
is set to the binary representation of address given by
.Fa cp
if it was a valid string.
This function supersedes
.Fn inet_addr
whose return value cannot distinguish between failure and a local
broadcast address.
.Pp
.Fa cp
should be a string in conventional dot notation of the form:
.Bd -literal -offset indent
a
a.b
a.b.c
a.b.c.d
.Ed
.Pp
Each part of the address can be represented in octal, decimal or
hexadeximal using the standard C notation: a leading 0 implies octal;
a leading 0x or 0X implies hex; a decimal number is assumed otherwise.
.Pp
If a one-part address is given, its value is placed in the network
address without any byte rearrangement.
When a two-part address -
.Li a.b -
is supplied, the last part is considered a 24-bit quantity and placed
in the bottom 3 bytes of
.Li addr->s_addr .
The first part is placed in the top byte of the address.
A three-part address -
.Li a.b.c -
is treated as if the last part was a 16-bit quantity.
The first two parts -
.Li a.b -
is put in the top 2 bytes and the last part in the low-end 2 bytes of
.Li addr->s_addr .
When a four-part address is supplied in
.Fa cp ,
each part is treated as a byte of data and assigned to the four bytes
of an Internet address.
In all four cases, the internet address in
.Li addr->s_addr
is stored in network byte order (big-endian) where the bytes are
ordered from left to right: i.e. 0, 1, 2, 3.
.Sh RETURN VALUES
The function returns 1 if
.Fa cp
was successfully interpreted as an IPv4 address or 0
if it was an invalid string.
.Sh SEE ALSO
.Xr inet_aton 3 ,
.Xr inet_addr 3 .

.Dt LWRES_INETPTON 3
.Os BIND9 9
.ds vT BIND9 Programmer's Manual
.Sh NAME
.Nm lwres_net_pton
.Nd lightweight resolver IP address conversion
.Sh SYNOPSIS
.Fd #include <lwres/net.h>
.Fd
.Ft int
.Fo lwres_net_pton
.Fa "int af"
.Fa "const char *src"
.Fa "void *dst"
.Fc
.Sh DESCRIPTION
.Fn lwres_net_pton
converts the presentation format of an IP address
.Fa src
to its representation in network format.
.Fa af
indicates the protocol family for the address
.Dv PF_INET
or
.Dv PF_INET6
and
.Fa src
is either a dotted decimal string for an IPv4 address or
a string in colon notation if it represents an IPv6 address.
RFC1884 defines the text notation to represent IPv6 addresses.
.Sh RETURN VALUES
.Fn lwres_net_pton
returns 1 if address
.Fa src
was valid for protocol family
.Fa af .
The network representation of the address is returned in
.Fa *dst .
Zero is returned if the address was invalid and -1 is returned if some
other error occurred.
.Fa *dst
is not altered for either of these errors.
.Sh SEE ALSO
.Xr inet_pton 3 ,
.Xr RFC1884 .
