This structure contains Windows Sockets address information for a network service or name space provider.

Syntax

typedef struct _CSADDR_INFO { 
  SOCKET_ADDRESS LocalAddr; 
  SOCKET_ADDRESS RemoteAddr; 
  INT iSocketType; 
  INT iProtocol; 
} CSADDR_INFO;

LocalAddr
Specifies a Windows Sockets local address.

In a client application, pass this address to the bind (Windows Sockets) function to obtain access to a network service.

In a network service, pass this address to the bind function so that the service is bound to the appropriate local address.

RemoteAddr
Specifies a Windows Sockets remote address. The following list shows uses for this remote address:
- You can use this remote address to connect to the service through the connect (Windows Sockets) function. This is useful if an application performs send/receive operations that involve connection-oriented protocols.
- You can use this remote address with the sendto function when you are communicating over a connectionless (datagram) protocol. If you are using a connectionless protocol, such as UDP, sendto is typically the way you pass data to the remote system.

iSocketType
Specifies the type of the Windows Socket. The following table shows the socket types that are defined in Winsock2.h.

Value	Socket type
SOCK_STREAM	Stream. This is a protocol that sends data as a stream of bytes, with no message boundaries.
SOCK_DGRAM	Datagram. This is a connectionless protocol. There is no virtual circuit setup. There are typically no reliability guarantees. Services use recvfrom to obtain datagrams. The listen and accept (Windows Sockets) functions do not work with datagrams.
SOCK_RDM	Reliably Delivered Message. This is a protocol that preserves message boundaries in data.
SOCK_SEQPACKET	Sequenced packet stream. This is a protocol that is essentially the same as SOCK_RDM.

iProtocol
Specifies a value to pass as the protocol parameter to the socket (Windows Sockets) function to open a socket for this service.
