Suspend a synchronization
#include <mmsync/mmsyncclient.h>
int mm_sync_suspend( mmsync_hdl_t *hdl, unsigned op_id, uint32_t flags )
Suspend a synchronization. You can do this to relieve contention on a device for a temporary purpose, such as accessing a file or starting playback quickly. This differs from cancelling a synchronization, which can be done if it's no longer needed or it begins to negatively impact performance.
