| * This file has test cases to test the recvfrom () call for 1-1 style sockets |
| * |
| * TEST1: Bad socket descriptor |
| * TEST2: Invalid socket |
| * TEST3: Invalid message pointer |
| * TEST4: On a listening socket |
| * TEST5: Reading on a socket that received SHUTDOWN |
| * TEST6: Reading the pending message on socket that received SHUTDOWN |
| * TEST7: No more message and association is shutdown |
