 Posted: Sat Jul 22, 2006 5:21 am Post subject: error reading from socket |
 |
|
I am trying to send an integer from Java Client to C++ server. I
figured out how to do the conversion. However, I have a problem reading
from the socket.
This is my code:
int DataInputStream::readInt()//reads one integer from the client
{
int32_t var1;
soc->recv((void*)&var1, 4);
var1 = ntohl(var1);
return var1;
}
I am assuming that I need a loop, but I cannot figure out which one. I
tried all cases that I could imagine, but none of them worked.
I MUST use recv function. Here is how it is defined:
int recv(void *buffer, int bufferLen)
throw(SocketException) {
int rtn;
if ((rtn = ::recv(sockDesc, (raw_type *) buffer, bufferLen, 0)) < 0)
{
throw SocketException("Received failed (recv())", true);
}
return rtn;
}
Any help is appreciated. |

What is your problem and where are your tests?

Exception specifications (other than throw()) tend to be more of
hindrance than a help. Consider what happens if another exception gets
throw.
