avr-libc: <inttypes.h>: Integer Type conversions AVR Libc Home Page AVR Libc Development Pages Main Page User Manual Library Reference FAQ Alphabetical Index Example Projects <inttypes.h>: Integer Type conversionsDetailed Description #include <inttypes.h> This header file includes the exact-width integer definitions from <stdint.h>, and extends them with additional facilities provided by the implementation. Currently, the extensions include two additional integer types that could hold a "far" pointer (i.e. a code pointer that can address more than 64 KB), as well as standard names for all printf and scanf formatting options that are supported by the <stdio.h>: Standard IO facilities. As the library does not support the full range of conversion specifiers from ISO 9899:1999, only those conversions that are actually implemented will be listed here. The idea behind these conversion macros is that, for each of the types defined by <stdint.h>, a macro will be supplied that portably allows formatting an object of that type in printf() or scanf() operations. Example: #include <inttypes.h> uint8_t smallval; int32_t longval; ... printf("The hexadecimal value of smallval is %" PRIx8 ", the decimal value of longval is %" PRId32 ".\n", smallval, longval); Far pointers for memory access >64K typedef int32_t int_farptr_t typedef uint32_t uint_farptr_t macros for printf and scanf format specifiers For C++, these are only included if __STDC_LIMIT_MACROS is defined before including <inttypes.h>. #define PRId8   "d" #define PRIdLEAST8   "d" #define PRIdFAST8   "d" #define PRIi8   "i" #define PRIiLEAST8   "i" #define PRIiFAST8   "i" #define PRId16   "d"
