29 * Format String Decoder
30 *
31 * This file provides the core engine for converting strings of format
32 * characters into formatted output. The various format dcmds invoke the
33 * mdb_fmt_print() function below with a target, address space identifier,
34 * address, count, and format character, and it reads the required data from
35 * the target and prints the formatted output to stdout. Since nearly two
36 * thirds of the format characters can be expressed as simple printf format
37 * strings, we implement the engine using the lookup table below. Each entry
38 * provides either a pointer to a printf format string or a pointer to a
39 * function to perform special processing. For the printf case, the
40 * corresponding data size in bytes is also supplied. The printf processing
41 * code handles 1, 2, 4, and 8-byte reads into an unsigned integer container
42 * of the given size, and then simply calls mdb_iob_printf with the integer
43 * and format string. This handles all printf cases, except when unsigned
44 * promotion of an integer type in the varargs list does not perform the
45 * conversion we require to get the proper result. With the current set of
46 * format characters, this case only occurs twice: we need a 4-byte float
47 * to get promoted to 8-byte double for the 'f' format so it can be
48 * correctly formatted by %f, and we need a 1-byte int8_t to get promoted
49 * with sign extension to a 4-byte int32_t for the 'v' format so it can be
50 * correctly formatted by %d. We provide explicit functions to handle these
51 * cases, as well as to handle special format characters such as 'i', etc.
52 * We also provide a cmd_formats() dcmd function below which prints a table
53 * of the output formats and their sizes. Format characters that provide
54 * custom functions provide their help description string explicitly. All
55 * the printf formats have their help strings generated automatically by
56 * our printf "unparser" mdb_iob_format2str().
