Function Documentation

Java_org_direct_1bt_BTUtils_currentTimeMillis()

jlong Java_org_direct_1bt_BTUtils_currentTimeMillis	(	JNIEnv *	env,
		jclass	clazz
	)

See http://man7.org/linux/man-pages/man2/clock_gettime.2.html

Regarding avoiding kernel via VDSO, see http://man7.org/linux/man-pages/man7/vdso.7.html, clock_gettime seems to be well supported at least on kernel >= 4.4. Only bfin and sh are missing, while ia64 seems to be complicated.
