I was asked, if I could expose some functionality of epgsearch (searching the EPG, calling the extended timer edit menu) to other plugins. I plan to do this, like the timeline plugin does to check for timer conflicts in other plugins:
Another way to tunnel information from one plugin to another is to use SetupParse("==epgsearch-tunnel-v1.0==",(char*)&data) for it. If, for some reason, the plugin doesn't know this tunnel (wrong version, wrong plugin), the function will most likely ignore this call and return false.
A far better way would be of course if VDR's cPlugin would have such a general purpose interface. My approach would be like this:
virtual bool ExtensionInterface(const char *ExtensionId, void *Data)
Plugins return false unless ExtensionId matches a known unique protocol ID. If the plugin supports this protocol, true will be returned in any case. If *Data is not NULL, it points to a protocol-specific buffer. If *Data is NULL, this is just a protocol-supported call.
cPluginManager should have methods to call ExtensionInterface for all plugins (broadcast-like), or for all plugins until one plugin returns true (find one that offers the interface).
@Klaus: I can implement that if interested.
