+NAME
+----
+tep_is_host_bigendian,tep_set_host_bigendian,tep_host_bigendian - Get / set the
+endianness of the machine running the current code.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+
+enum *tep_endian* {
+	TEP_LITTLE_ENDIAN = 0,
+	TEP_BIG_ENDIAN
+};
+
+int *tep_is_host_bigendian*(struct tep_handle pass:[*]_tep_);
+void *tep_set_host_bigendian*(struct tep_handle pass:[*]_tep_, enum tep_endian _endian_);
+int tep_host_bigendian(void);
+--
+
+DESCRIPTION
+-----------
+The _tep_is_host_bigendian()_ function returns the endianness of the the machine
+running the current code. The _tep_ argument is the trace event parser context.
+
+The _tep_set_host_bigendian()_ set the endianness of the machine running the code.
+The _tep_ argument is trace event parser context. The _endian_ argument is the
+endianness:
+[verse]
+--
+	_TEP_LITTLE_ENDIAN_ - the machine is little endian,
+	_TEP_BIG_ENDIAN_ - the machine is big endian.
+--
+
+RETURN VALUE
+------------
+The _tep_is_host_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_host_bigendian(tep, TEP_LITTLE_ENDIAN);
+...
+	if (TEP_BIG_ENDIAN == tep_is_host_bigendian(tep)) {
+		/* The local host is big endian */
+	} else {
+		/* The local host is little endian */
+	}
