 This function allows the plugin to restrict the kinds of events where the plugin's `extract_fields` method will be called. Valid event source names are the ones returned by the `get_event_source` function of plugins with event sourcing capabilitiy, or `syscall` for indicating support to non-plugin events. The return value should be a string containing a json array of compatible event sources, with memory owned by the plugin. Here's an example:

The return value is an array of integers representing the event types that the plugin is capable of processing for field extraction. Events with types that are not present in the returned list will not be received by the plugin. The event types follow the enumeration from the [libscap specific](#libscap-event-block-specification).

 Receives an event from the current capture and parses its content. The plugin is guaranteed to receive an event at most once, after any operation related the event sourcing capability, and before any other operation related to the field extraction capability. The returned rc value should be `SS_PLUGIN_SUCCESS` (0) on success, `SS_PLUGIN_FAILURE` (1) on failure.

 ### get_async_events
 
 ```
-const char* get_async_events()   [Required: yes]
+const char* plugin_get_async_events()   [Required: yes]
 ```
 
 Return a string describing the name list of all asynchronous events that this plugin is capable of pushing into a live event stream. The framework can reject async events produced by a plugin if their name is not on the name list returned by this function. The return value should be a string containing a json array of compatible event sources, with memory owned by the plugin.

 ```
 
 Sets a function handler that allows the plugin to send events asynchronously to its owner during a live event capture. The handler is a thread-safe function that can be invoked concurrently by multiple threads. The asynchronous events must be encoded as an async event type (code 402) as for the [libscap specific](#libscap-event-block-specification). The returned rc value should be `SS_PLUGIN_SUCCESS` (0) on success, `SS_PLUGIN_FAILURE` (1) on failure.
