c++ - WinSock: server receives bytes from telnet, not from client -

-

i trying write client connects server written labmate. can make connection both telnet , own client program using winsock. telnet sends , receives commands fine, client can receive , not send any, despite not receiving error upon starting send().

a snippet of client code:

// after connection. // receive message first. recv_size = recv(socket_test, server_resp, strlen(server_resp), null); // check later. server_resp[recv_size] = '\0'; printf(server_resp); // prints initial send server fine. printf("\n");   int bytes; char testmess[100]; // contains test message send. cin >> testmess; bytes = send(socket_test, testmess, strlen(testmess), 0); printf("%d", bytes); // displays right number.

i'm wondering difference between send methods between telnet , winsock send() be? have socket configured standard sock_stream type.
