80  * Buffer types:
81  *
82  * Many of the routines in this module require the user to supply a
83  * buffer into which the desired strings may be written. These are
84  * all arrays of characters, and might be defined as simple arrays
85  * of char. The problem with that approach is that when such an array
86  * is passed to a function, the C language considers it to have the
87  * type (char *), without any regard to its length. Not all of our
88  * buffers have the same length, and we want to ensure that the compiler
89  * will refuse to compile code that passes the wrong type of buffer to
90  * a given routine. The solution is to define the buffers as unions
91  * that contain the needed array, and then to pass the given union
92  * by address. The compiler will catch attempts to pass the wrong type
93  * of pointer, and the size of a structure/union is implicit in its type.
94  *
95  * A nice side effect of this approach is that we can use a union with
96  * multiple buffers to handle the cases where a given routine needs
97  * more than one type of buffer. The end result is a single buffer large
98  * enough to handle any of the subcases, but no larger.
99  */

101 /*
102  * Size of buffer used by conv_invalid_val():
103  *
104  * Various values that can't be matched to a symbolic definition are converted
105  * to a numeric string.
106  *
107  * The buffer size reflects the maximum number of digits needed to
108  * display an integer as text, plus a trailing null, and with room for
109  * a leading "0x" if hexidecimal display is selected.
110  *
111  * The 32-bit version of this requires 12 characters, and the 64-bit version
112  * needs 22. By using the larger value for both, we can have a single
113  * definition, which is necessary for code that is ELFCLASS independent. A
114  * nice side benefit is that it lets us dispense with a large number of 32/64
115  * buffer size definitions that build off CONV_INV_BUFSIZE, and the macros
116  * that would then be needed.

583  *	in consecutive order. The final item corresponds to the value given
584  *	by ds_topval. Zero (0) Msg values can be used to represent missing
585  *	values. Entries with a 0 are quietly ignored.
586  *
587  *    conv_ds_vd_t (ds_type == CONV_DS_VD)
588  *	This structure employs a NULL terminated array of Val_desc structs.
589  *	Each Val_desc supplies a mapping from a value in the range
590  *	(ds_baseval <= value <= ds_topval). The values described need not
591  *	be consecutive, and can be sparse. ds_baseval does not need to
592  *	correspond to the first item, and ds_topval need not correspond to
593  *	the final item.
594  *
595  *    conv_ds_vd2_t (ds_type == CONV_DS_VD2)
596  *	This structure employs a NULL terminated array of Val_desc2 structs,
597  *	rather than Val_desc, adding the ability to specify OSABI and machine
