## Detailed Description

Manage device preferences, start services, pairing and activation.

## Function Documentation

## ◆ lockdownd_activate()

lockdownd_error_t lockdownd_activate | ( | lockdownd_client_t | client,
|  | plist_t | activation_record
| ) |  |

Activates the device.

Only works within an open session. The ActivationRecord plist dictionary must be obtained using the activation protocol requesting from Apple's https webservice.

Parameters

  client | The lockdown client
  activation_record | The activation record plist dictionary

Returns
  LOCKDOWN_E_SUCCESS on success, LOCKDOWN_E_INVALID_ARG when client or activation_record is NULL, LOCKDOWN_E_NO_RUNNING_SESSION if no session is open, LOCKDOWN_E_PLIST_ERROR if the received plist is broken, LOCKDOWN_E_ACTIVATION_FAILED if the activation failed, LOCKDOWN_E_INVALID_ACTIVATION_RECORD if the device reports that the activation_record is invalid

## ◆ lockdownd_client_free()

lockdownd_error_t lockdownd_client_free | ( | lockdownd_client_t | client | ) |

Closes the lockdownd client session if one is running and frees up the lockdownd_client struct.

Parameters

  client | The lockdown client

Returns
  LOCKDOWN_E_SUCCESS on success, LOCKDOWN_E_INVALID_ARG when client is NULL

## ◆ lockdownd_client_new()

lockdownd_error_t lockdownd_client_new | ( | idevice_t | device,
|  | lockdownd_client_t * | client,
|  | const char * | label
| ) |  |

Creates a new lockdownd client for the device.

Note
  This function does not pair with the device or start a session. This has to be done manually by the caller after the client is created. The device disconnects automatically if the lockdown connection idles for more than 10 seconds. Make sure to call lockdownd_client_free() as soon as the connection is no longer needed.

Parameters

  device | The device to create a lockdownd client for
  client | The pointer to the location of the new lockdownd_client
  label | The label to use for communication. Usually the program name.

Returns
  LOCKDOWN_E_SUCCESS on success, LOCKDOWN_E_INVALID_ARG when client is NULL

## ◆ lockdownd_client_new_with_handshake()

lockdownd_error_t lockdownd_client_new_with_handshake | ( | idevice_t | device,
|  | lockdownd_client_t * | client,

| ) |  |

Creates a new lockdownd client for the device and starts initial handshake.

The handshake consists out of query_type, validate_pair, pair and start_session calls. It uses the internal pairing record management.

Note
  The device disconnects automatically if the lockdown connection idles for more than 10 seconds. Make sure to call lockdownd_client_free() as soon as the connection is no longer needed.

Parameters

  device | The device to create a lockdownd client for
  client | The pointer to the location of the new lockdownd_client
  label | The label to use for communication. Usually the program name. Pass NULL to disable sending the label in requests to lockdownd.
