Hi,
I am trying to get the "metadata" from ParaView by connecting to the socket.
I'm having an issue where I am correctly sending the command to send the data
but I'm not receiving the length value or string correctly. Below is my method
how I am currently trying to get the length value:
// In the main program //
command = 2;
if(-1 == send(socket, &command, sizeof(command), 0))
exit(1);
int size;
unsigned long long length;
if((size = Receive(socket, &length, sizeof(unsigned long long))
<= 0)
exit(1);
cout << size << endl;
cout << length << endl;
// Receive function //
int Receive( cons int sk, void* data, int len)
{
char* buffer = reinterpret_cast<char*>(data);
int total = 0;
do
{
int nRecvd = recv(socket,
buffered+total, len-total, 0);
if(nRecvd == 0)
{
cout << "No
Data Received" << endl;
exit(1);
}
if(nRecvd == -1)
{
cout << "Error"
<< endl;
exit(1);
}
total += nRecvd;
}while(total < len);
return total;
}
Now in the source code of the MobileSocketPlugin, I added a printf to show the
value of "length" before it is sent over the socket. When I run my code, it
succeeds without an error but the value of my "length" is not equal. For
example, if I connect and run my code immediately after starting up ParaView,
it always sends a value of "1733" but I receive a value of "7443178323969"
every time. I'm really not sure what I need to change to get this correct. If
someone could point me in the right direction on what I need to be doing to
receive the metadata through MobileSocketPlugin, I would greatly appreciate it!
Thanks,
Travis J. Bueter
