  17 /* Macro for defining "auto-load" functions.
  18  * Note that this is self-modifying code *gasp*.
  19  * The first invocation of a routine will trigger the loading of
  20  * the DLL.  This will then be followed by the discovery of
  21  * the procedure's entry point, which is placed into the location
  22  * pointed to by the stack pointer.  This code then changes
  23  * the "call" operand which invoked it to a "jmp" which will
  24  * transfer directly to the DLL function on the next invocation.
  25  *
  26  * Subsequent calls to routines whose transfer address has not been
  27  * determined will skip the "load the dll" step, starting at the
  28  * "discovery of the entry point" step.
  29  *
  30  * So, immediately following the the call to one of the above routines
  31  * we have:
  32  *  DLL info (4/8 bytes) Pointer to a block of information concerning
  33  *                       the DLL (see below).
  34  *  DLL notimp (2 bytes) Bool value flagging that non-existence of this
  35  *                       function is not a fatal error.
  36  *  DLL error (2 bytes)  Error value returned if function load fails.
  37  *                       Depends on the return type of the function.
  38  *                       Default is 0 == BOOL FALSE or == HANDLE NULL or
  39  *                       == Pointer NULL.
  40  *  func addr (8 bytes)  Address of the actual Win32 function.  For the
  41  *                       reason why this is necessary, see the below
  42  *                       description of the load_state.
  43  *  func name (n bytes)  asciz string containing the name of the function
  44  *                       to be loaded.
  45  *
  46  * The DLL info block consists of the following
  47  *  load_state (4/8 bytes) Pointer to a word containing the routine used
  48  *                       to eventually invoke the function.  Initially
  49  *                       points to an init function which loads the DLL,
  50  *                       gets the process's load address, changes the contents
  51  *                       here to point to the function address, and changes
  52  *                       the address argument of the initial jmp call.
  53  *                       On x86_64, the jmp is not tweaked directly.  Rather,
  54  *                       the address of the Win32 function is stored in the
  55  *                       aforementioned Win32 function address slot and fetched
  56  *                       there for a jmp *%rax call.  This indirection is
  57  *                       necessary to workaround the lack of a jmp opcode with
  58  *                       offset values > 32 bit.  If the initialization has
  59  *                       been done, only the load part is done.
  60  *  DLL handle (4/8 bytes) The handle to use when loading the DLL.
  61  *  DLL locker (4 bytes) Word to use to avoid multi-thread access during
  62  *                       initialization.
  63  *  extra init (4/8 bytes) Extra initialization function.
  64  *  DLL name (n bytes)   asciz string containing the name of the DLL.
