我在windows中使用了linux部分代码来建立RDB通信。虽然套接字打开成功,但我无法将套接字与定义的 IP 地址绑定。Linux 和 Windows 在 socket 上是否有任何限制?
这是我的代码,
SOCKET sock;
SOCKET sClient;
struct sockaddr_in server;
char szServer128; // Server to connect to
char szBuffer204800; // allocate on heap
sClient = udpsock_open(&server, szServer, DEFAULT_RX_PORT);
int udpsock_open(struct sockaddr_in *psa, char *ipv4, uint16_t port) {
WSADATA wsaData;
int opt;
int domain = AF_INET;
int type = SOCK_DGRAM;
int proto = IPPROTO_UDP;
sClient = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (sClient 0)
printf(" WSAStartup Successful %I64d\n", sClient);
else
printf("Failed. Error Code : %d\n", WSAGetLastError());
// Prepare a socket to listen for connections
if ((sock = WSASocket(domain, type, 0, NULL, 0, WSA_FLAG_OVERLAPPED)) INVALID_SOCKET)
{
printf("WSASocket() failed with error %d\n", WSAGetLastError());
return 1;
}
else
{
printf("WSASocket() is OK!\n");
}
if (sock < 0)
{
//rtos_log ( LOG_ERR, "Failed to open socket %m" );
printf("Failed to open socket %I64d\n", sock);
return -1;
}
set_reuse(sock);
memset(psa, 0x00, sizeof(struct sockaddr_in));
psa->sin_family = domain;
psa->sin_port = htons(port);
psa->sin_addr.s_addr = inet_addr(ipv4);
if (bind(sock, ( struct sockaddr *)psa, sizeof(struct sockaddr_in)) < 0)
{
printf("Failed to bind socket Error: %d\n", WSAGetLastError());
closesocket(sock);
WSACleanup();
return -4;
}
opt = 1;
char buf[2048];
DWORD dwBytesRet;
//ioctlsocket(sock, FIONBIO, &opt)
if (WSAIoctl(sock, SIO_ADDRESS_LIST_QUERY,NULL,0, buf,2048, &dwBytesRet,NULL,NULL) == SOCKET_ERROR)
{
printf("ioctlsocket() failed with error %d\n", WSAGetLastError());
return 1;
}
else
{
printf("ioctlsocket() is OK!\n");
}
return sock;
}
