## Detailed Description

Synchronize data classes with a device and computer.

## Enumeration Type Documentation

## ◆ mobilesync_sync_type_t

enum mobilesync_sync_type_t

The sync type of the current sync session.

Enumerator
MOBILESYNC_SYNC_TYPE_FAST | Fast-sync requires that only the changes made since the last synchronization should be reported by the computer.
MOBILESYNC_SYNC_TYPE_SLOW | Slow-sync requires that all data from the computer needs to be synchronized/sent.
MOBILESYNC_SYNC_TYPE_RESET | Reset-sync signals that the computer should send all data again.

## Function Documentation
