| 90 | * DETAILED DESCRIPTION |
| 91 | * This is a Phase I test for the link(2) system call. It is intended |
| 92 | * to provide a limited exposure of the system call, for now. It |
| 93 | * should/will be extended when full functional tests are written for |
| 94 | * link(2). |
| 95 | * |
| 96 | * Setup: |
| 97 | * Setup signal handling. |
| 98 | * Pause for SIGUSR1 if option specified. |
| 99 | * |
| 100 | * Test: |
| 101 | * Loop if the proper options are given. |
| 102 | * Execute system call |
| 103 | * Check return code, if system call failed (return=-1) |
| 104 | * Log the errno and Issue a FAIL message. |
| 105 | * Otherwise, Issue a PASS message. |
| 106 | * |
| 107 | * Cleanup: |
| 108 | * Print errno log and/or timing stats if options given |
| 109 | * |
