The CSADDR_INFO structure contains Windows Sockets address information for a network service or name space provider. The GetAddressByName function obtains Windows Sockets address information using CSADDR_INFO structures.
typedef struct _CSADDR_INFO {
SOCKET_ADDRESS LocalAddr;
SOCKET_ADDRESS RemoteAddr;
INT iSocketType;
INT iProtocol;
} CSADDR_INFO;
Members
LocalAddr
Specifies a Windows Sockets local address.
In a client application, pass this address to the bind 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. There are several uses for this remote address:
ˇYou can use this remote address to connect to the service via the connect function. This is useful if an application performs send/receive operations that involve connection-oriented protocols.
ˇYou 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 socket types are defined in WINSOCK.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 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 function to open a socket for this service.
