  26 // transition - SecurityServer client library transition code.
  27 //
  28 // These are the functions that implement CssmClient methods in terms of
  29 // MIG IPC client calls, plus their supporting machinery.
  30 //
  31 // WARNING! HERE BE DRAGONS!
  32 // This code involves moderately arcane magic including (but not limited to)
  33 // dancing macros paired off with self-maintaining stack objects. Don't take
  34 // anything for granted! Be very afraid of ALL-CAPS names. Your best bet is
  35 // probably to stick with the existing patterns.
  36 //
  37 // Dragons, the sequel.  You just don't go killing of that kind of prose, so
  38 // we'll continue the saga here with a bit of an update.  In transitioning
  39 // into securityd there are a couple of steps.  The current setup is there
  40 // to allow Security.framework to have 32 and 64 bit clients and either
  41 // big or little endian.  Data is packaged up as hand-generated XDR, which
  42 // means it's also in network byte-order.
  43 //
  44 // CSSM_HANDLEs have remained longs in the 64 bit transition to keep the
  45 // optimization option open to allow cssm modules to hand back pointers as
  46 // handles.  Since we don't identify the client, handles across ipc will
  47 // remain 32 bit.  Handles you see here are passed out by securityd, and
  48 // are clipped and expanded in this layer (high bits always zero).
