* File: pidns10.c |
|
* * |
|
* * Description: |
|
* * The pidns10.c testcase verifies inside the container, if kill(-1, signal) |
|
* * fails with ESRCH when there are no processes in container. |
|
* * |
|
* * Test Assertion & Strategy: |
|
* * Create a PID namespace container. |
|
* * Invoke kill(-1, SIGUSR1) inside container and check return code and error. |
|
* * kill() should have failed;except swapper & init, no process is inside. |
|
* * |
|
* * Usage: <for command-line> |
|
* * pidns10 |
