61  *	- server stub performs NDR_M_OP_UNMARSHALL+NDR_DIR_IN

63  *	- server function returns w/ TOP-MOST arg structure modified

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

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