See also
  idevice_new_with_options

Parameters

  device | Upon calling this function, a pointer to a location of type idevice_t. On successful return, this location will be populated.

Creates an idevice_t structure for the device specified by UDID, if the device is available, with the given lookup options.

Note
  The resulting idevice_t structure has to be freed with idevice_free() if it is no longer used.

Parameters

  device | Upon calling this function, a pointer to a location of type idevice_t. On successful return, this location will be populated.
  udid | The UDID to match.
  options | Specifies what connection types should be considered when looking up devices. Accepts bitwise or'ed values of idevice_options.

If a device is available both via USBMUX and network, it will select the USB connection. This behavior can be changed by adding IDEVICE_LOOKUP_PREFER_NETWORK to the options in which case it will select the network connection.
