+NAME
+----
+tep_file_bigendian,tep_set_file_bigendian - Get / set the endianness of the
+raw data being accessed by the tep handler.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+
+enum *tep_endian* {
+	TEP_LITTLE_ENDIAN = 0,
+	TEP_BIG_ENDIAN
+};
+
+int *tep_file_bigendian*(struct tep_handle pass:[*]_tep_);
+void *tep_set_file_bigendian*(struct tep_handle pass:[*]_tep_, enum tep_endian _endian_);
+
+--
+DESCRIPTION
+-----------
+The _tep_file_bigendian()_ function returns the endianness of the raw data,
+being accessed by the tep handler. The _tep_ argument is trace event parser context.
+
+The _tep_set_file_bigendian()_ set the endianness of raw data being accessed
+by the tep handler. The _tep_ argument is trace event parser context.
+[verse]
+--
+The _endian_ argument is the endianness:
+	_TEP_LITTLE_ENDIAN_ - the raw data is in little endian format,
+	_TEP_BIG_ENDIAN_ - the raw data is in big endian format.
+--
+RETURN VALUE
+------------
+The _tep_file_bigendian()_ function returns _TEP_LITTLE_ENDIAN_ or _TEP_BIG_ENDIAN_.
+
+EXAMPLE
+-------
+[source,c]
+--
+#include <event-parse.h>
+...
+struct tep_handle *tep = tep_alloc();
+...
+	tep_set_file_bigendian(tep, TEP_LITTLE_ENDIAN);
+...
+	if (TEP_BIG_ENDIAN == tep_file_bigendian(tep)) {
+		/* The raw data is in big endian */
+	} else {
+		/* The raw data is in little endian */
+	}
