40 /** \defgroup avr_inttypes <inttypes.h>: Integer Type conversions
41  \code #include <inttypes.h> \endcode
42 
43  This header file includes the exact-width integer definitions from
44  <tt><stdint.h></tt>, and extends them with additional facilities
45  provided by the implementation.
46 
47  Currently, the extensions include two additional integer types
48  that could hold a "far" pointer (i.e. a code pointer that can
49  address more than 64 KB), as well as standard names for all printf
50  and scanf formatting options that are supported by the \ref avr_stdio.
51  As the library does not support the full range of conversion
52  specifiers from ISO 9899:1999, only those conversions that are
53  actually implemented will be listed here.
54 
55  The idea behind these conversion macros is that, for each of the
56  types defined by <stdint.h>, a macro will be supplied that portably
57  allows formatting an object of that type in printf() or scanf()
58  operations. Example:
59 
60  \code
61  #include <inttypes.h>
62 
63  uint8_t smallval;
64  int32_t longval;
65  ...
66  printf("The hexadecimal value of smallval is %" PRIx8
67  ", the decimal value of longval is %" PRId32 ".\n",
68  smallval, longval);
69  \endcode
