An IPv4 address 28 of INADDR_ANY specifies that the connection is made to 29 all of the network stacks on the platform. Specifying a 30 specific IPv4 address restricts the connection to the 31 network stack supporting that address. Specifying zero 32 for the port causes the network layer to assign a port 33 number from the dynamic range. Specifying a specific 34 port number causes the network layer to use that port. 35 36 @param[in] namelen Specifies the length in bytes of the sockaddr structure. 37 38 @return The bind routine returns zero (0) if successful and -1 upon failure. 39 In the case of an error, ::errno contains more information. 40 **/ 41 int 42 bind ( 43 IN int s, 44 IN const struct sockaddr * name, 45 IN socklen_t namelen 46 ) 47 { 48 int BindStatus; 49 EFI_SOCKET_PROTOCOL * pSocketProtocol; 50 51 // Locate the context for this socket 52 pSocketProtocol = BslFdToSocketProtocol ( s, NULL, &errno ); 53 if ( NULL != pSocketProtocol ) { 54 55 // Bind the socket 56 (void) pSocketProtocol->pfnBind ( pSocketProtocol, 57 name, 58 namelen, 59 &errno ); 60 } 61 62 // Return the operation stauts 63 BindStatus = ( 0 == errno ) ? 0 : -1; 64 return BindStatus; 65 } 66
