## Detailed Description

Linux host run loop interface.

- [host imp]
- [extends IPlugFrame]
- [released: 3.6.8]

On Linux the host has to provide this interface to the plug-in as there's no global event run loop defined as on other platforms.

A plug-in can register an event handler for a file descriptor. The host has to call the event handler when the file descriptor is marked readable.

A plug-in also can register a timer which will be called repeatedly until it is unregistered.
