Apps that do network communication

Requesting network connection

If your application needs to do network communication and it appears that there is no physical network connection (e.g. gethostbyname() fails for a valid name) then:

• Call boinc_need_network(). This will alert the user that a network connection is needed.
• Periodically call boinc_network_poll() until it returns zero.
• Do whatever communication is needed.
• When done, call boinc_network_done(). This enables the hangup of a modem connection, if needed.

void boinc_need_network();
int boinc_network_poll();
void boinc_network_done();
