| * This file has test cases to test the connect () call for 1-1 style sockets |
| * |
| * TEST1: Bad socket descriptor |
| * TEST2: Invalid socket |
| * TEST3: Invalid address |
| * TEST4: Invalid address length |
| * TEST5: Invalid address family |
| * TEST6: Valid blocking connect |
| * TEST7: Connect when accept queue is full |
| * TEST8: On a listening socket |
| * TEST9: On established socket |
| * TEST10: Connect to re-establish a closed association. |
