/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
The following encoding technique is taken from RFC 1521 by Borenstein
and Freed. It is reproduced here in a slightly edited form for
convenience.
A 65-character subset of US-ASCII is used, enabling 6 bits to be
represented per printable character. (The extra 65th character, "=",
is used to signify a special processing function.)
The encoding process represents 24-bit groups of input bits as output
strings of 4 encoded characters. Proceeding from left to right, a
24-bit input group is formed by concatenating 3 8-bit input groups.
These 24 bits are then treated as 4 concatenated 6-bit groups, each
of which is translated into a single digit in the base64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable
characters. The character referenced by the index is placed in the
output string.
Table 1: The Base64 Alphabet
Value Encoding Value Encoding Value Encoding Value Encoding
0 A 17 R 34 i 51 z
1 B 18 S 35 j 52 0
2 C 19 T 36 k 53 1
3 D 20 U 37 l 54 2
4 E 21 V 38 m 55 3
5 F 22 W 39 n 56 4
6 G 23 X 40 o 57 5
7 H 24 Y 41 p 58 6
8 I 25 Z 42 q 59 7
9 J 26 a 43 r 60 8
10 K 27 b 44 s 61 9
11 L 28 c 45 t 62 +
12 M 29 d 46 u 63 /
13 N 30 e 47 v
14 O 31 f 48 w (pad) =
15 P 32 g 49 x
16 Q 33 h 50 y
Special processing is performed if fewer than 24 bits are available
at the end of the data being encoded. A full encoding quantum is
always completed at the end of a quantity. When fewer than 24 input
bits are available in an input group, zero bits are added (on the
right) to form an integral number of 6-bit groups. Padding at the
end of the data is performed using the '=' character.
Since all base64 input is an integral number of octets, only the
-------------------------------------------------
following cases can arise:
(1) the final quantum of encoding input is an integral
multiple of 24 bits; here, the final unit of encoded
output will be an integral multiple of 4 characters
with no "=" padding,
(2) the final quantum of encoding input is exactly 8 bits;
here, the final unit of encoded output will be two
characters followed by two "=" padding characters, or
(3) the final quantum of encoding input is exactly 16 bits;
here, the final unit of encoded output will be three
characters followed by one "=" padding character.

documentation for the bind routine is available online for reference.
@param [in] s Socket file descriptor returned from ::socket.
@param [in] name Address of a sockaddr structure that contains the
connection point on the local machine. An IPv4 address
of INADDR_ANY specifies that the connection is made to
all of the network stacks on the platform. Specifying a
specific IPv4 address restricts the connection to the
network stack supporting that address. Specifying zero
for the port causes the network layer to assign a port
number from the dynamic range. Specifying a specific
port number causes the network layer to use that port.
@param [in] namelen Specifies the length in bytes of the sockaddr structure.
@returns The bind routine returns zero (0) if successful and -1 upon failure.

Connect to a remote system via the network.
The ::connect routine attempts to establish a connection to a
socket on the local or remote system using the specified address.
The
<a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/connect.html">POSIX</a>
documentation is available online.
There are three states associated with a connection:
<ul>
<li>Not connected</li>
<li>Connection in progress</li>
<li>Connected</li>
</ul>
In the "Not connected" state, calls to ::connect start the connection
processing and update the state to "Connection in progress". During
the "Connection in progress" state, connect polls for connection completion
and moves the state to "Connected" after the connection is established.
Note that these states are only visible when the file descriptor is marked
with O_NONBLOCK. Also, the POLL_WRITE bit is set when the connection
completes and may be used by poll or select as an indicator to call
connect again.
@param [in] s Socket file descriptor returned from ::socket.
@param [in] address Network address of the remote system
@param [in] address_len Length of the remote network address
@returns ::connect returns zero if successful and -1 when an error occurs.

# Network services, Internet style
#
# Note that it is presently the policy of IANA to assign a single well-known
# port number for both TCP and UDP; hence, officially ports have two entries
# even if the protocol doesn't support UDP operations.
#
# Updated from http://www.iana.org/assignments/port-numbers and other
# sources like http://www.freebsd.org/cgi/cvsweb.cgi/src/etc/services .
# New ports will be added on request if they have been officially assigned
# by IANA and used in the real-world or are needed by a debian package.
# If you need a huge list of used numbers please install the nmap package.

documentation for the socket routine is available online for reference.
@param [in] pSocketProtocol Address of the socket protocol structure.
@param [in] domain Select the family of protocols for the client or server
application.
@param [in] type Specifies how to make the network connection. The following values
are supported:
<ul>
<li>
SOCK_STREAM - Connect to TCP, provides a byte stream
that is manipluated by read, recv, send and write.
</li>
<li>
SOCK_SEQPACKET - Connect to TCP, provides sequenced packet stream
that is manipulated by read, recv, send and write.

<li>
SOCK_DGRAM - Connect to UDP, provides a datagram service that is
manipulated by recvfrom and sendto.

@param [in] protocol Specifies the lower layer protocol to use. The following
values are supported:
<ul>
<li>IPPROTO_TCP</li> - This value must be combined with SOCK_STREAM.</li>
