5 * This file has test cases to test the send() call for 1-1 style sockets
6 *
7 * TEST1: Bad socket descriptor
8 * TEST2: Invalid socket
9 * TEST3: On a listening socket
10 * TEST4: On a closed association
11 * TEST5: Invalid message address
12 * TEST6: send from client to server
13 * TEST7: send from server to client
14 * TEST8: sending partial data from a buffer
