+================

+NAME
+----
+tep_filter_alloc,tep_filter_free,tep_filter_reset - Create / free / reset an event filter.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+
+struct tep_event_filter pass:[*]*tep_filter_alloc*(struct tep_handle pass:[*]_tep_);
+void *tep_filter_free*(struct tep_event_filter pass:[*]_filter_);
+void *tep_filter_reset*(struct tep_event_filter pass:[*]_filter_);
+--
+
+DESCRIPTION
+-----------
+The _tep_filter_alloc()_ function creates a new event filter. The _tep_ argument
+is the trace event parser context.
+
+The _tep_filter_free()_ function frees an event filter and all resources that it 
+had used. 
+
+The _tep_filter_reset()_ function removes all rules from an event filter and 
+resets it.
+
+RETURN VALUE
+------------
+The _tep_filter_alloc()_ function returns a pointer to the newly created event
+filter, or NULL in case of an error.
+
+EXAMPLE
+-------
+[source,c]
+--
+#include <event-parse.h>
+...
+struct tep_handle *tep = tep_alloc();
+...
+struct tep_event_filter *filter = tep_filter_alloc(tep);
+if (filter == NULL) {
+	/* Failed to create the filter */
+}
+...
+tep_filter_reset(filter);
+...
+tep_filter_free(filter);
+...
