72  * Buffer types:
73  *
74  * Many of the routines in this module require the user to supply a
75  * buffer into which the desired strings may be written. These are
76  * all arrays of characters, and might be defined as simple arrays
77  * of char. The problem with that approach is that when such an array
78  * is passed to a function, the C language considers it to have the
79  * type (char *), without any regard to its length. Not all of our
80  * buffers have the same length, and we want to ensure that the compiler
81  * will refuse to compile code that passes the wrong type of buffer to
82  * a given routine. The solution is to define the buffers as unions
83  * that contain the needed array, and then to pass the given union
84  * by address. The compiler will catch attempts to pass the wrong type
85  * of pointer, and the size of a structure/union is implicit in its type.
86  *
87  * A nice side effect of this approach is that we can use a union with
88  * multiple buffers to handle the cases where a given routine needs
89  * more than one type of buffer. The end result is a single buffer large
90  * enough to handle any of the subcases, but no larger.
91  */

93 /*
94  * Size of buffer used by conv_invalid_val():
95  *
96  * Various values that can't be matched to a symbolic definition are converted
97  * to a numeric string.
98  *
99  * The buffer size reflects the maximum number of digits needed to
100  * display an integer as text, plus a trailing null, and with room for
101  * a leading "0x" if hexidecimal display is selected.
102  *
103  * The 32-bit version of this requires 12 characters, and the 64-bit version
104  * needs 22. By using the larger value for both, we can have a single
105  * definition, which is necessary for code that is ELFCLASS independent. A
106  * nice side benefit is that it lets us dispense with a large number of 32/64
107  * buffer size definitions that build off CONV_INV_BUFSIZE, and the macros
108  * that would then be needed.

449  *	Style of strings used by file(1).

454  *   CF
455  *	Canonical Form: The string is exactly the same as the name
456  *	of the #define macro that defines it in the public header files.
457  *	(e.g. STB_LOCAL, not LOCL, LOCAL, LOC, or any other variation).
458  *
459  *   CFNP
460  *	No Prefix Canonical Form: The same strings supplied by CF,
461  *	but without their standard prefix. (e.g. LOCAL, instead of STT_LOCAL).
462  *
463  *   NF
464  *	Natural Form: The form of the strings that might typically be entered
465  *	via a keyboard by an interactive user. These are usually the strings
466  *	from CFNP, converted to lowercase, although in some cases they may
467  *	take some other "natural" form. In command completion applications,
468  *	lowercase strings appear less formal, and are easier on the eye.

470  * Every routine is required to have a default style. The others are optional,
471  * and may not be provided if not needed. If a given conversion routine does
472  * not support alternative strings for a given CONV_FMT_ALT type, it silently
473  * ignores the request and supplies the default set. This means that a utility
474  * like dump(1) is free to specify a style like DUMP to every conversion
475  * routine. It will receive its special strings if there are any, and
476  * the defaults otherwise.

543  * any of the variants safely. In C++, it would be a virtual base class.

546  *	ds_type: Identifies the variant

553  *	to consecutive ELF values. The first item in the array is the Msg
554  *	code for the value given by ds_baseval. Consecutive strings follow
555  *	in consecutive order. The final item corresponds to the value given
556  *	by ds_topval. Zero (0) Msg values can be used to represent missing
557  *	values. Entries with a 0 are quietly ignored.
558  *
559  *    conv_ds_vd_t (ds_type == CONV_DS_VD)
560  *	This structure employs a NULL terminated array of Val_desc structs.
561  *	Each Val_desc supplies a mapping from a value in the range
562  *	(ds_baseval <= value <= ds_topval). The values described need not
563  *	be consecutive, and can be sparse. ds_baseval does not need to
564  *	correspond to the first item, and ds_topval need not correspond to
565  *	the final item.
566  *
567  *    conv_ds_vd2_t (ds_type == CONV_DS_VD2)
568  *	This structure employs a NULL terminated array of Val_desc2 structs,
569  *	rather than Val_desc, adding the ability to specify OSABI and machine
