26 /* this module apparently provides an implementation of DCE/RPC over a

28 * documentation are available (in on-line form) from the X-Open group.
30 * this module should provide a level of abstraction between SMB
31 * and DCE/RPC, while minimising the amount of mallocs, unnecessary
32 * data copies, and network traffic.
34 * in this version, which takes a "let's learn what's going on and
35 * get something running" approach, there is additional network
36 * traffic generated, but the code should be easier to understand...
38 * ... if you read the docs. or stare at packets for weeks on end.
