+DESCRIPTION
+-----------
+These functions can be used to find a field and retrieve its value.
+
+The _tep_get_any_field_val()_ function searches in the _record_ for a field
+with _name_, part of the _event_. If the field is found, its value is stored in
+_val_. If there is an error and _err_ is not zero, then an error string is
+written into _s_.
+
+The _tep_get_common_field_val()_ function does the same as
+_tep_get_any_field_val()_, but searches only in the common fields. This works
+for any event as all events include the common fields.
+
+The _tep_get_field_val()_ function does the same as _tep_get_any_field_val()_,
+but searches only in the event specific fields.
+
+The _tep_get_field_raw()_ function searches in the _record_ for a field with
+_name_, part of the _event_. If the field is found, a pointer to where the field
+exists in the record's raw data is returned. The size of the data is stored in
+_len_. If there is an error and _err_ is not zero, then an error string is
+written into _s_.
+
+RETURN VALUE
+------------
+The _tep_get_any_field_val()_, _tep_get_common_field_val()_ and
+_tep_get_field_val()_ functions return 0 on success, or -1 in case of an error.
+
+The _tep_get_field_raw()_ function returns a pointer to field's raw data, and
+places the length of this data in _len_. In case of an error NULL is returned.
+
+EXAMPLE
+-------
+[source,c]
+--
+#include <event-parse.h>
+#include <trace-seq.h>
+...
+struct tep_handle *tep = tep_alloc();
+...
+struct tep_event *event = tep_find_event_by_name(tep, "kvm", "kvm_exit");
+...
+void process_record(struct tep_record *record)
+{
+	int len;
+	char *comm;
+	struct tep_event_format *event;
+	unsigned long long val;
+
+	event = tep_find_event_by_record(pevent, record);
+	if (event != NULL) {
+		if (tep_get_common_field_val(NULL, event, "common_type",
+		 			     record, &val, 0) == 0) {
+			/* Got the value of common type field */
+		}
+		if (tep_get_field_val(NULL, event, "pid", record, &val, 0) == 0) {
+			/* Got the value of pid specific field */
+		}
+		comm = tep_get_field_raw(NULL, event, "comm", record, &len, 0);
+		if (comm != NULL) {
+			/* Got a pointer to the comm event specific field */
+		}
+	}
+}
