| * |
| * TEST TITLE : Basic test for madvise(2) |
| * |
| * TEST CASE TOTAL : 5 |
| * |
| * CPU TYPES : Intel(R) XEON(TM) |
| * |
| * AUTHOR : Sumit Sharma |
| * |
| * CO-PILOT : |
| * |
| * DATE STARTED : 13/05/2004 |
| * |
| * TEST CASES |
| * |
| * 1.) madvise(2) advices...(See Description) |
| * |
| * INPUT SPECIFICATIONS |
| * The standard options for system call tests are accepted. |
| * (See the parse_opts(3) man page). |
| * |
| * OUTPUT SPECIFICATIONS |
| * Output describing whether test cases passed or failed. |
| *$ |
| * ENVIRONMENTAL NEEDS |
| * None |
| * |
| * SPECIAL PROCEDURAL REQUIREMENTS |
| * None |
| * |
| * DETAILED DESCRIPTION |
| * This is a test case for madvise(2) system call. |
| * It tests madvise(2) with combinations of advice values. |
| * No error should be returned. |
| * |
| * Total 5 Test Cases :- |
| * (1) Test Case for MADV_NORMAL |
| * (2) Test Case for MADV_RANDOM |
| * (3) Test Case for MADV_SEQUENTIAL |
| * (4) Test Case for MADV_WILLNEED |
| * (5) Test Case for MADV_DONTNEED |
| * |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * Execute system call |
| * Check return code, if system call failed (return=-1) |
| * Log the errno and Issue a FAIL message. |
| * Otherwise, Issue a PASS message. |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
