Solution 1

From MSDN[^] (assuming you are using connection oriented Windows Sockets):

For connection-oriented sockets (type SOCK_STREAM for example), calling recv will return as much data as is currently available—up to the size of the buffer specified.

Solution 2

The status returned from recv() will tell you if more data is available, so you just keep reading until you have all the data that is waiting. See here[^] for full information on this function.

Take Network Library to work with sockets. It is easy to find.
