Socket send binary data error

[demonofnight]

Hi,

I'm implementing socket on c++, but when i transfer some binary data from one side to another it dont works well.
If i send a file with 279mb on the other side it's with 300mb.
I think it's some kind of trash on the memory sequence, but i dont know how to send the correct size.

Here is the code:
Send ->
if(myfile.is_open()){
while(!myfile.eof()){
// getline(myfile, line);
myfile.read(echoString, 1024);
sock.send(echoString, sizeof(echoString));
}

Receive ->
while ((recvMsgSize = sock->recv(echoBuffer, RCVBUFSIZE)) > 0) { // Zero means
// end of transmission
printf("%.*s", recvMsgSize, echoBuffer);
// Echo message back to client
//sock->send(echoBuffer, recvMsgSize);
}

Someone can help me?

You are reading (up to) 1024 bytes but it may only read a smaller amount. If you were to use readsome() instead of read() the return value would be the actual number of characters, which you could then pass to the send() function.
