+ * rwbytype.d - read/write bytes by vnode type.
+ * Written using DTrace (Solaris 10 3/05).
+ *
+ * This program identifies the vnode type of read/write activity - whether
+ * that is for regular files, sockets, character special devices, etc.
+ *
+ * $Id: rwbytype.d 3 2007-08-01 10:50:08Z brendan $
+ *
+ * USAGE: rwbytype.d # hit Ctrl-C to end sample
+ *
+ * FIELDS:
+ * PID number of rwbytype
+ * CMD process name
+ * VTYPE vnode type (describes I/O type)
+ * DIR direction (Read/Write)
+ * BYTES bytes transferred
