55  * Normal sequence:
56  *	- Application calls client-side stub w/ TOP-MOST arg structure

58  *	- PDU conveyed (request, aka call, aka query)
59  *	- server stub performs NDR_M_OP_UNMARSHALL+NDR_DIR_IN
60  *	- server function called w/ TOP-MOST arg structure
61  *	- server function returns w/ TOP-MOST arg structure modified

67  * An interface is a sequence of top-most constructs.  Each top-most
68  * construct corresponds to one parameter, either argument or return
69  * value.
70  *
71  * A top-most construct is a sequence of outer constructs.  The first
72  * outer construct is the referent of the argument, and the subsequent
73  * outer constructs are descendents referenced by pointers from prior
74  * constructs.
75  *
76  * An outer construct is a sequence of variable-sized info, fixed-sized
77  * data, and variable-sized data.

81  * Terminology
82  *
83  * The ALL UPPER CASE terms recur in the DCE/RPC documentation.
84  * The mixed-case names have been introduced as a reading aid.
85  *
86  * Size		The size of an array in elements. Think of this
87  *		as the amount to malloc().
88  *
89  * Length	The number of elements of an array which are significant
90  *		Think of this as the amount to bcopy().
91  *
92  * Known	Size/length is known at build time.
93  *
94  * Determined	Size/length is determined at run time.
95  *
96  * FIXED	The Size and Length are Known.
97  *		Think of this as a string constant or a DOS 8.3 file name.
98  *		char array[] = "A Constant Size/Length";
99  *
100  * CONFORMANT	The Size is Determined. Length is the same as Size.
101  *		Think of this as strdup().
102  *		char *array = strdup("Something");
103  *
104  * VARYING	The Size is Known. The Length is determined.
105  *		Think of this as a strcpy() of a variable length string
106  *		into a fixed length buffer:
107  *		char array[100];
108  *		strcpy(array, "very short string");
109  *
110  * VARYING/CONFORMANT
111  *		The Size is Determined. The Length is separately Determined.
112  *		Think of this like:
113  *		char *array = malloc(size);
114  *		strcpy(array, "short string");
115  *
116  * STRING	Strings can be CONFORMANT, VARYING, or CONFORMANT/VARYING.
117  *		A string is fundamentally an array with the last
118  *		significant element some sort of NULL.
