/*++
Routine Description:
Conditionally accept a connection based on the return value of a condition
function, and optionally create and/or join a socket group.
Arguments:
s - A descriptor identiying a socket which is listening for
connections after a WSPListen().
addr - An optional pointer to a buffer which receives the address
of the connecting entity, as known to the service
provider. The exact format of the addr arguement is
determined by the address family established when the
socket was created.
addrlen - An optional pointer to an integer which contains the
length of the address addr.
lpfnCondition - The procedure instance address of an optional, WinSock 2
client supplied condition function which will make an
accept/reject decision based on the caller information
passed in as parameters, and optionally creaetd and/or
join a socket group by assigning an appropriate value to
the result parameter of this function.
dwCallbackData - Callback data to be passed back to the WinSock 2 client as
a condition function parameter. This parameter is not
interpreted by the service provider.
lpErrno - A pointer to the error code.
Return Value:
If no error occurs, WSPAccept() returns a value of type SOCKET which is a
descriptor for the accepted socket. Otherwise, a value of INVALID_SOCKET
is returned, and a specific error code is available in lpErrno.

Routine Description:
WSPAddressToString() converts a SOCKADDR structure into a human-readable
string representation of the address. This is intended to be used mainly
for display purposes. If the caller wishes the translation to be done by a
particular provider, it should supply the corresponding WSAPROTOCOL_INFO
struct in the lpProtocolInfo parameter.
Arguments:
lpsaAddress - points to a SOCKADDR structure to translate into a string.
dwAddressLength - the length of the Address SOCKADDR.
lpProtocolInfo - (optional) the WSAPROTOCOL_INFO struct for a particular
provider.
lpszAddressString - a buffer which receives the human-readable address
string.
lpdwAddressStringLength - on input, the length of the AddressString buffer.
On output, returns the length of the string
actually copied into the buffer.

Routine Description:

Arguments:
s - Identifies the socket. This is the same socket that was
specified when the overlapped operation was started by a
call to WSPRecv(), WSPRecvFrom(), WSPSend(), WSPSendTo(), or
WSPIoctl().
lpOverlapped - Points to a WSAOVERLAPPED structure that was specified
when the overlapped operation was started.
lpcbTransfer - Points to a 32-bit variable that receives the number of
bytes that were actually transferred by a send or receive
operation, or by WSPIoctl().
fWait - Specifies whether the function should wait for the pending
overlapped operation to complete. If TRUE, the function
does not return until the operation has been completed. If
FALSE and the operation is still pending, the function
returns FALSE and lperrno is WSA_IO_INCOMPLETE.

flags that supplement the completion status. If the

for lpFlags parameter.
lpErrno - A pointer to the error code.

completed or the overlapped operation completed but with errors, or that

Routine Description:
Disable sends and/or receives on a socket.
Arguments:
s - A descriptor identifying a socket.
how - A flag that describes what types of operation will no longer be
allowed.
lpErrno - A pointer to the error code.
Return Value:
If no error occurs, WSPShutdown() returns 0. Otherwise, a value of
SOCKET_ERROR is returned, and a specific error code is available in
lpErrno.

Routine Description:
Initialize internal data and prepare sockets for usage. Must be called
before any other socket routine.
Arguments:
lpProtocolInfo - Supplies a pointer to a WSAPROTOCOL_INFOA struct that
defines the characteristics of the socket to be created.
g - Supplies the identifier of the socket group which the new
socket is to join.
dwFlags - Supplies the socket attribute specification.
lpErrno - Returns the error code
Return Value:
WSPSocket() returns zero if successful. Otherwise it returns an error code
as outlined in the SPI.

Routine Description:
WSPStringToAddress() converts a human-readable string to a socket address
structure (SOCKADDR) suitable for pass to Windows Sockets routines which
take such a structure. If the caller wishes the translation to be done by
a particular provider, it should supply the corresponding WSAPROTOCOL_INFO
struct in the lpProtocolInfo parameter.
Arguments:
AddressString - points to the zero-terminated human-readable string to
convert.
AddressFamily - the address family to which the string belongs.
lpProtocolInfo - (optional) the WSAPROTOCOL_INFO struct for a particular
provider.
Address - a buffer which is filled with a single SOCKADDR structure.
lpAddressLength - The length of the Address buffer. Returns the size of
the resultant SOCKADDR structure.
Return Value:
The return value is 0 if the operation was successful. Otherwise the value
SOCKET_ERROR is returned.
