| 21 | * EXECUTED BY : anyone |
| 22 | * |
| 23 | * TEST TITLE : testing error conditions for sched_getparam(2) |
| 24 | * |
| 25 | * TEST CASE TOTAL : 3 |
| 26 | * |
| 27 | * AUTHOR : Saji Kumar.V.R <saji.kumar@wipro.com> |
| 28 | * |
| 29 | * SIGNALS |
| 30 | * Uses SIGUSR1 to pause before test if option set. |
| 31 | * (See the parse_opts(3) man page). |
| 32 | * |
| 33 | * DESCRIPTION |
| 34 | * Verify that, |
| 35 | * 1) sched_getparam(2) returns -1 and sets errno to ESRCH if the |
| 36 | * process with specified pid could not be found |
| 37 | * 2) sched_getparam(2) returns -1 and sets errno to EINVAL if |
| 38 | * the parameter pid is an invalid value (-1) |
| 39 | * 3) sched_getparam(2) returns -1 and sets errno to EINVAL if the |
| 40 | * parameter p is an invalid address |
| 41 | * |
| 42 | * ALGORITHM |
| 43 | * Setup: |
| 44 | * Setup signal handling. |
| 45 | * Pause for SIGUSR1 if option specified. |
| 46 | * |
| 47 | * Test: |
| 48 | * Loop if the proper options are given. |
| 49 | * Execute system call |
| 50 | * Check return code, if (system call failed (return=-1)) & |
| 51 | * (errno set == expected errno) |
| 52 | * Issue sys call fails with expected return value and errno. |
| 53 | * Otherwise, |
| 54 | * Issue sys call returns unexpected value. |
| 55 | * |
| 56 | * Cleanup: |
| 57 | * Print errno log and/or timing stats if options given |
| 58 | * |
| 59 | * USAGE: <for command-line> |
| 60 | * sched_getparam03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p] |
| 61 | * where, -c n : Run n copies concurrently. |
| 62 | * -e : Turn on errno logging. |
| 63 | * -h : Show help screen |
| 64 | * -f : Turn off functional testing |
| 65 | * -i n : Execute test n times. |
| 66 | * -I x : Execute test for x seconds. |
| 67 | * -p : Pause for SIGUSR1 before starting |
| 68 | * -P x : Pause for x seconds between iterations. |
| 69 | * -t : Turn on syscall timing. |
| 70 | * |
