| * This file has test cases to test the shutdown() call for 1-1 style sockets |
| * |
| * TEST1: Bad socket descriptor |
| * TEST2: Invalid socket |
| * TEST3: shutdown with SHUT_WR flag to disable new send |
| * TEST4: shutdown with SHUT_RD flag to disable new receive |
| * TEST5: shutdown with SHUT_RDWR flag to disable new receive/send |
| * TEST6: Unconnected socket |
