WSAAddressToString ?

[Z.K.]

I am trying to make a Bluetooth application and I am using sockets with
RFCOMM. I have pased some code and the output below. I hard code a
Bluetooth MAC address then use WSAStringToAddress and WSAAddressToString
afterwards to make sure it is correct. I get a bunch of garbage at
the start of result and I am not sure why.

Also, when using the connect function I get an error and -1 is returned,
but the message says that the operation was completed successfully. Why
is that?

Z.K.

output:

Successful Opening Socket
result = ╠╠╠╠╠╠╠╠╠00:20:e0:7f:12:07
status = -1

error:
The operation completed successfully.

error:
The operation completed successfully.

code:

SOCKADDR_BTH addr;
memset(&addr,0,sizeof(addr));
int status = 0;
int s = 0;
char BTAddress[18] = "00:20:e0:7f:12:07";
addr.addressFamily = AF_BTH;
addr.port = BT_PORT_ANY;
addr.btAddr = 0;

WSAStringToAddress(BTAddress,AF_BTH,NULL,(LPSOCKADDR)&addr,(LPINT)64);

char result[1];

WSAAddressToString((LPSOCKADDR)&addr,(DWORD)sizeof(addr),NULL,result,(LPDWORD)sizeof(result));

printf("\nresult = %s\n",result);

//connect to server
status = connect(s, (SOCKADDR*)&addr, sizeof(SOCKADDR_BTH));

//send a message
if(status == 0)
MessageBox(NULL,"Sucess Connecting to Socket","Connect Dialog",MB_OK);
else
{
printf("status = %d\n",status);
MessageBox(NULL,"Error Connecting to Socket","Connect Dialog",MB_OK);
PrintLastError();
}

void PrintLastError(void)
{
LPVOID lpMsgBuf;

FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER|
FORMAT_MESSAGE_FROM_SYSTEM|
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL, GetLastError(), 0, (LPTSTR) &lpMsgBuf,
0, NULL);

fprintf(stderr, "\n\nerror: \n%s\n", lpMsgBuf);
printf("\n\nerror: \n%s\n", lpMsgBuf);
CString temp;
temp.Format("%s",lpMsgBuf);
MessageBox(NULL,temp,"Error Dialog",MB_OK);

}

I am not sure, you're able to specify mac address into WSAStringToAddress
function. Try to play with this snippet of code, it does correct
conversation from string into address structure, and back,

void sometest(void)
{
SOCKADDR_IN addr = {0};

int status = 0;
int s = 0;

char BTAddress[18] = "192.168.0.13";
char result[64] = {0};
DWORD dwSizeOfStr = sizeof(result);
int nSizeOfInput = sizeof(addr);

addr.sin_family = AF_INET;

status = WSAStringToAddressA(BTAddress, AF_INET, NULL, (LPSOCKADDR)&addr,
&nSizeOfInput);

if (status == 0)
{
status = WSAAddressToStringA((LPSOCKADDR)&addr, nSizeOfInput, NULL,
result, &dwSizeOfStr);

printf("\nresult = %s\n",result);
}
}

Thanks a lot, that works a lot better for me.
