对基于UDP的网络通信而言，首先需要创建ISocket接口，
ISocket *mySocket;
mySocket = INETMGR_OpenSocket(pMe->pINetMgr, AEE_SOCK_STREAM);
if(!mySocket) {
DBGPRINTF(“Error value: %x”, INETMGR_GetLastError(pMe->pINetMgr));
}
然后，就可以发送数据包了
Void SendPacket(App* pMe){
retVal = ISOCKET_SendTo(pMe->pISocket, (byte*)"HelloWorld",
sizeof("HelloWorld"), 0, pMe->inAddr, HTONS(pMe->port));
switch(retVal) {
case AEE_NET_WOULDBLOCK:
ISOCKET_Writeable(pMe->pISocket, (PFNNOTIFY)SendPacket, pMe);
return;
// Some sort of network error
case AEE_NET_ERROR:
DBGPRINTF("Network Error");
break;
default:
if(retVal == sizeof(“HelloWorld”))
//Success
else
// Some other error
}
}
在接收数据之前，先要绑定客户端的端口。
static void SetUpNetwork(CVocApp* pMe) {
int retVal;
// Bind to the correct port and ip address
retVal = ISOCKET_Bind(pMe->pIRecvSocket, HTONL(AEE_BREW_LOOPBACK), HTONS(PORT));
// Check the return value of ISOCKET_Bind() and display necessary message
switch(retVal) {
// Socket not ready yet
case AEE_NET_WOULDBLOCK:
ISOCKET_Writeable(pMe->pIRecvSocket, (PFNNOTIFY)SetUpNetwork, pMe);
break;
// Succesfully connected
case AEE_NET_SUCCESS:
ISOCKET_Readable(pMe->pIRecvSocket, (PFNNOTIFY)ReadInData, pMe);
break;
// Something went wrong, print error to logger
default:
DBGPRINTF("retVal %d", ISOCKET_GetLastError(pMe->pIRecvSocket));
break;
}
}
然后，就可以通过UDP接收数据了，
static void ReadInData(App* pMe) {
int ret;
// When data is ready, receive data
ret = ISOCKET_RecvFrom(pMe->pIRecvSocket, (void*)&pMe->indata, sizeof(pMe->indata), ISOCKET_FLAG_SENDTO_WAKEUP|ISOCKET_FLAG_SENDTO_URGENT, NULL, NULL);
// Data integrity checks
if(ret < 0) {
DBGPRINTF("error %d", ISOCKET_GetLastError(pMe->pIRecvSocket));
}
// Have socket continue to listen
ISOCKET_Readable(pMe->pIRecvSocket, (PFNNOTIFY)ReadInData, pMe);
}
通信完毕，需要使用ISOCKET_Release()来释放接口对象。
对基于TCP的网络通信而言，同样，首先需要创建ISocket接口，
ISocket *mySocket;
mySocket = INETMGR_OpenSocket(pMe->pINetMgr, AEE_SOCK_STREAM);
if(!mySocket) {
DBGPRINTF(“Error value: %x”, INETMGR_GetLastError(pMe->pINetMgr));
}
然后，建立数据连接，并监测连接的网络状态，如果连接成功则发送数据
ISOCKET_Connect(pMe->pISocket,HTONL(myIP),HTONS(myPort),(PFNCONNECTCB)ConnectionMade, pMe);
static void ConnectionMade(myApp* pMe, int error) {
//Check error code
switch(error) {
case AEE_NET_ETIMEDOUT:
// Connection timed out
break;
case AEE_NET_SUCCESS:
// Send Some data
if(AEE_NET_WOULDBLOCK==ISOCKET_Write(pMe->pISocket,(byte*)"helloworld", sizeof("helloworld")) {
ISOCKET_Writeable(pMe->pISocket, (PFNNOTIFY) SendDataCB, pMe);
}
break;
default:
// Some other Network error
break;
}
}
