/* this structure is just a wrapper for a string, the only reason we
   bother with this is that it allows us to check the length provided
   on the wire in testsuite test code to ensure that we are
   terminating names in the same way that win2003 is. The *ONLY* time
   you should ever look at the 'private_length' field in this
   structure is inside compliance test code, in all other cases just
   use the null terminated char* as the definitive definition of the
   string

   also note that this structure is only used in packets where there
   is an explicit length provided on the wire (hence the name). That
   length is placed in 'private_length'. For packets where the length
   is always determined by NULL or packet termination a normal char*
   is used in the structure definition.
