MobileDevice Library is used by [[iTunes]] to transfer data between iPhone and computer over both USB and WiFi connections.

* Location: <code>C:\Program Files\Common Files\Apple\Mobile Device Support\iTunesMobileDevice.dll</code> (<code>Program Files (x86)</code> on 64-bit)
  +
* Supporting CoreFoundation.dll (used for CFStringRef, CFPropertyListRef management) is located in the same dir (when using [[iTunes]] prior 9.0).
  +
* For [[iTunes]] 9.0, the location of CoreFoundation.dll is stored in '''InstallDir''' registry value under '''HKLM\SOFTWARE\Apple Inc.\Apple Application Support''' registry key.

==== Obtaining address ====
<pre>
 
  +
In order to obtain the address of a usable private function in MobileDevice, you will have to be able to understand x86-64 assembly to reverse engineer it. These methods differ slightly based on platform due to how dynamically linked libraries handle position independent code.
/* ----------------------------------------------------------------------------
 
* MobileDevice.h - interface to MobileDevice.framework
 
* ------------------------------------------------------------------------- */

=====Mac OS X (MobileDevice.framework)=====
#ifndef MOBILEDEVICE_H
 
  +
A private function is not marked as exported in the mach-o symbol table. This means it cannot be called by simply linking against the library. To call unexported functions, the mach-o symbol table must be stepped through manually to find the offset of a particular function call. Calls can be verified by checking against the offset of the name inside the name table.
#define MOBILEDEVICE_H
 
   
  +
=====Windows (MobileDevice.dll)=====
#ifdef __cplusplus
 
  +
Unlike OS X's dynamically linkable libraries, Windows dynamic libraries do not support position independent code in the same manner. A private function will not have its name in the exported symbol table, so in a debugger, like GDB, it will show up as part of another function. However, you will know that it is a separate function as a new stack frame is set up.

===Locking the Device for Sync===
 
When iTunes sends a new song to the device, the device shows a "Sync in progress" screen and when complete, the Music app on the device re-reads the iTunesDB file so it picks up the new song.
 
 
To get this behaviour, first start the notification service:
 
<pre>SOCKET socket;
 
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);</pre>
 
 
Now we post a notificaton message to signal that we are going to start a sync:
 
<pre>AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncWillStart"), NULL);</pre>
 
 
Next we open the itunes lock file:
 
<pre>afc_file_ref lockref;
 
AFCFileRefOpen(conn, "/com.apple.itunes.lock_sync", 2, &lockref);</pre>
 
 
Now post a notification to say we are going to lock this file, and try and lock it.
 
If the AFCFileRefLock call fails, pause and repeat.
 
<pre>AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncLockRequest"), NULL);
 
mach_error_t error = AFCFileRefLock(conn, lockref);</pre>
 
 
When the file is successfully locked, post another notification, and stop the notification service.
 
<pre>AMDPostNotification(socket,CFSTR("com.apple.itunes-mobdev.syncDidStart"), NULL);
 
AMDShutdownNotificationProxy(socket);</pre>
 
 
Now the sync can proceed, so copy your files across and make the changes to the iTunesDB.
 
 
To release the lock, start the notification system again, unlock and close the lock file, and send a sync finished notification message:
 
 
<pre>AFCFileRefUnlock(conn, lockref);
 
AFCFileRefClose(conn, lockref);
 
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);
 
AMDPostNotification(socket, &CFSTR("com.apple.itunes-mobdev.syncDidFinish"), NULL);
 
AMDShutdownNotificationProxy(socket);</pre>
 
 
NOTE: You may find that starting the notification_proxy service once and once only at the start of your app and using the same socket in calls to AMDPostNotification works better. iTunes opens and closes the notification_proxy regularly, but it appears to be a bit flakey when you open/close it all the time.

MobileDevice Library is used by iTunes to transfer data between iPhone and computer over both USB and WiFi connections.

Windows: iTunesMobileDevice.dll

  • Location: C:\Program Files\Common Files\Apple\Mobile Device Support\iTunesMobileDevice.dll (Program Files (x86) on 64-bit)
  • Supporting CoreFoundation.dll (used for CFStringRef, CFPropertyListRef management) is located in the same dir (when using iTunes prior 9.0).
  • For iTunes 9.0, the location of CoreFoundation.dll is stored in InstallDir registry value under HKLM\SOFTWARE\Apple Inc.\Apple Application Support registry key.

Mac OS X: MobileDevice.framework

  • Location: /System/Library/PrivateFrameworks/MobileDevice.framework
  • Export command: nm /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice

Library Interfaces

  • libimobiledevice (provides the same functionality on GNU/Linux)
  • mobiledevice (command line utility for interacting with MobileDevice Framework)
  • SDMMobileDevice (OS X framework written in C that can be used interchangeably with Apple's private framework MobileDevice.framework)
  • MobileDeviceAccess (similar to above, but written in Objective-C)
  • MobileDevice.h (old reverse engineered header for interfacing with MobileDevice library)


Private Functions

Obtaining address

In order to obtain the address of a usable private function in MobileDevice, you will have to be able to understand x86-64 assembly to reverse engineer it. These methods differ slightly based on platform due to how dynamically linked libraries handle position independent code.

Mac OS X (MobileDevice.framework)

A private function is not marked as exported in the mach-o symbol table. This means it cannot be called by simply linking against the library. To call unexported functions, the mach-o symbol table must be stepped through manually to find the offset of a particular function call. Calls can be verified by checking against the offset of the name inside the name table.

Windows (MobileDevice.dll)

Unlike OS X's dynamically linkable libraries, Windows dynamic libraries do not support position independent code in the same manner. A private function will not have its name in the exported symbol table, so in a debugger, like GDB, it will show up as part of another function. However, you will know that it is a separate function as a new stack frame is set up.
