| 25 | * FS_Handler |
| 26 | * |
| 27 | * Description: |
| 28 | * Handler routine passed to the fsprobe module. This handler is |
| 29 | * called immediately after a poll of all the FileServers has taken |
| 30 | * place. All it needs to know is exported by the fsprobe module, |
| 31 | * namely the data structure where the probe results are stored. |
| 32 | * |
| 33 | * Arguments: |
| 34 | * None. |
| 35 | * |
| 36 | * Returns: |
| 37 | * 0 on success, |
| 38 | * -1 otherwise. |
| 39 | * |
| 40 | * Environment: |
| 41 | * See above. All we do now is print out what we got. |
| 42 | * |
| 43 | * Side Effects: |
| 44 | * As advertised. |
