31 Notes on format of format strings:
32 * whitespace is ignored
33 * each "group" consists of an optional count (defaults to 1),
34 an optional byte-order marker (defaults to H, "host-native"),
35 and a data-type specifier.
36 * when unpacking, each variable argument is a pointer to the
37 appropriate number of objects of the appropriate type.
38 * when packing, each variable argument is an object of the
39 appropriate type if the count is omitted, or a pointer to the
40 appropriate number of objects of the appropriate type if the
42 * the buffer supplied to pack/unpack must be of sufficient length
43 to hold all the data, or the behavior is unspecified.
44 * the file provided to the "f" versions of the functions must be
45 open in the appropriate mode, or the behavior is unspecified.
46 * the file supplied to funpackf must be of sufficient length to
47 hold all the data, or the behavior is unspecified.
48 * the behavior of all functions is unspecified if the format string
49 is incorrectly-formed.
52 x skipped byte; no corresponding argument
54 s two-byte two's-complement integer
55 i four-byte two's-complement integer
56 l eight-byte two's-complement integer
57 f four-byte IEEE754 float
58 d eight-byte IEEE754 double
60 Byte-order specifiers:
63 H host's native byte order
