Assuming the sends take place over a TCP connection, any number of things. In generally, you cannot rely on anything about the length of the string returned from recv(N) except that: it will not be greater than N it will not be less than 1 unless the connection has been lost If you expect a particular number of bytes, you need to call recv() multiple times and collect the returned strings until you have as many bytes as you wanted.
