| /* |
| * NAME |
| * mlock01.c |
| * |
| * DESCRIPTION |
| * Test to see that mlock works |
| *$ |
| * ALGORITHM |
| * test 1: |
| * Call mlock with various valid addresses and lengths. No |
| * error should be returned |
| * |
| * USAGE: <for command-line> |
| * -c n Run n copies concurrently |
| * -e Turn on errno logging |
| * -f Turn off functional testing |
| * -h Show this help screen |
| * -i n Execute test n times |
| * -I x Execute test for x seconds |
| * -p Pause for SIGUSR1 before starting |
| * -P x Pause for x seconds between iterations |
| * -t Turn on syscall timing |
| * |
| * HISTORY |
| * 06/2002 Written by Paul Larson |
