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

/*
 * Size of buffer used by conv_invalid_val():
 *
 * Various values that can't be matched to a symbolic definition are converted
 * to a numeric string.
 *
 * The buffer size reflects the maximum number of digits needed to
 * display an integer as text, plus a trailing null, and with room for
 * a leading "0x" if hexidecimal display is selected.
