Errors

Returns -1 if an error is encountered and sets errno to the error value.

  • EACCES: the application manifest does not include the WifiConfig capability.

  • EAGAIN: the Wi-Fi device isn't ready yet.

  • ENETDOWN: the Wi-Fi network interface is unavailable.

Any other errno may also be specified; such errors aren't deterministic and the same behavior might not be retained through system updates.

Return value

Returns the number of networks found, or -1 for failure, in which case errno is set to the error value.

Application manifest requirements

The application manifest must include the WifiConfig capability.
