24// Several member functions of the following classes are called with a pointer to
25// an object from a global list (cTimer, cChannel, cRecording or cEvent). In these
26// cases the core VDR code holds a lock on the respective list. While in general a
27// plugin should only work with the objects and data that is explicitly given to it
28// in the function call, the called function may itself set a read lock (not a write
29// lock!) on this list, because read locks can be nested. It may also set read locks
30// (not write locks!) on higher order lists.
31// For instance, a function that is called with a cChannel may lock cRecordings and/or
32// cSchedules (which contains cEvent objects), but not cTimers. If a plugin needs to
33// set locks of its own (on mutexes defined inside the plugin code), it shall do so
34// after setting any locks on VDR's global lists, and it shall always set these
35// locks in the same sequence, to avoid deadlocks.
