Re: [vdr] Making a cList object thread safe?

what is the best way to make a cList derived object thread safe?

You have to protect all functions of your object which are dealing with the list (reading and/or writing) with a cMutex.

Alternatively you could use a cRwLock, but this is more complicated. It should be the prefered solution if you have a lot concurrent read accesses but only few writes (e.g. like EPG data).

There are already some synchronisation methods in VDR (cMutex, cThreadLock,...). Is there any preferred method to solve my problem? Is there any plugin that already handled and solved this?

I think there are a lot, e.g. MP3 plugin. But VDR core it self has some examples, e.g. cRemote or cCaDescriptorHandler
