87  * Terminology
88  *
89  * The ALL UPPER CASE terms recur in the DCE/RPC documentation.
90  * The mixed-case names have been introduced as a reading aid.
91  *
92  * Size		The size of an array in elements. Think of this
93  *		as the amount to malloc().
94  *
95  * Length	The number of elements of an array which are significant
96  *		Think of this as the amount to bcopy().
97  *
98  * Known	Size/length is known at build time.
99  *
100  * Determined	Size/length is determined at run time.
101  *
102  * FIXED	The Size and Length are Known.
103  *		Think of this as a string constant or a DOS 8.3 file name.
104  *		char array[] = "A Constant Size/Length";
105  *
106  * CONFORMANT	The Size is Determined. Length is the same as Size.
107  *		Think of this as strdup().
108  *		char *array = strdup("Something");
109  *
110  * VARYING	The Size is Known. The Length is determined.
111  *		Think of this as a strcpy() of a variable length string
112  *		into a fixed length buffer:
113  *		char array[100];
114  *		strcpy(array, "very short string");
115  *
116  * VARYING/CONFORMANT
117  *		The Size is Determined. The Length is separately Determined.
118  *		Think of this like:
119  *		char *array = malloc(size);
120  *		strcpy(array, "short string");
121  *
122  * STRING	Strings can be CONFORMANT, VARYING, or CONFORMANT/VARYING.
123  *		A string is fundamentally an array with the last
124  *		significant element some sort of NULL.
