| 5 | If your application needs to do network communication and it appears that there is no physical network connection |
| 6 | (e.g. `gethostbyname()` fails for a valid name) then: |
| 7 | |
| 8 | * Call `boinc_need_network()`. This will alert the user that a network connection is needed. |
| 9 | * Periodically call `boinc_network_poll()` until it returns zero. |
| 10 | * Do whatever communication is needed. |
| 11 | * When done, call `boinc_network_done()`. This enables the hangup of a modem connection, if needed. |
