| * NAME |
| * dup201.c |
| * |
| * DESCRIPTION |
| * Negative tests for dup2() with bad fd (EBADF) |
| * |
| * ALGORITHM |
| * Setup: |
| * a. Setup signal handling. |
| * b. Pause for SIGUSR1 if option specified. |
| * |
| * Test: |
| * a. Loop if the proper options are given. |
| * b. Loop through the test cases |
| * c. Execute dup2() system call |
| * d. Check return code, if system call failed (return=-1), test |
| * for EBADF. |
| * |
| * Cleanup: |
| * a. Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * dup201 [-c n] [-e] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * |
| * HISTORY |
| * 07/2001 Ported by Wayne Boyer |
| * 01/2002 Removed EMFILE test - Paul Larson |
| * |
| * RESTRICTIONS |
| * NONE |
