In order to bind a local DECnet address to a socket, the parameter name should point to a sockaddr_dn structure.
#include <ws2dnet.h>
int WSAAPI bind (SOCKET s, const struct sockaddr_dn FAR * name, int namelen);
int WSAAPI WSPBind ( SOCKET s, const struct sockaddr_dn FAR * name, int namelen, int FAR * lpErrno );
name | A pointer to a sockaddr_dn structure which contains the DECnet address to be bound to this socket. |
