All rights reserved. * * We build on <machine/types.h> rather than <sys/types.h> in order to * minimize the global namespace pollution (i.e., we'd like to define * *only* those identifiers that the C standard mandates should be * defined by <stdint.h>). Using <machine/types.h> means that (at * least as of January 2001) all of the extra macros that do get * #defined by #include'ing <stdint.h> are in the implementor's * namespace ("_[A-Z].*" or "__.*"). * * The reason that we do #include the relevant ...types.h instead of * creating several "competing" typedefs is to make header collisions * less likely during the transition to C99. * * Caveat: There are still five extra typedef's defined by doing it * this way: "u_int{8,16,32,64}_t" and "register_t". Might be * fixable via pre- and post- #defines, but probably not worth it. */ #ifndef _STDINT_H_ #define _STDINT_H_ #include <machine/types.h> /* from ISO/IEC 988:1999 spec */ /* 7.18.1.1 Exact-width integer types */ /* int8_t is defined in <machine/types.h> */ /* int16_t is defined in <machine/types.h> */ /* int32_t is defined in <machine/types.h> */ /* int64_t is defined in <machine/types.h> */ typedef u_int8_t uint8_t; /* u_int8_t is defined in <machine/types.h> */ typedef u_int16_t uint16_t; /* u_int16_t is defined in <machine/types.h> */ typedef u_int32_t uint32_t; /* u_int32_t is defined in <machine/types.h> */ typedef u_int64_t uint64_t; /* u_int64_t is defined in <machine/types.h> */ /* 7.18.1.2 Minumun-width integer types */ typedef int8_t int_least8_t; typedef int16_t int_least16_t; typedef int32_t int_least32_t; typedef int64_t int_least64_t; typedef uint8_t uint_least8_t; typedef uint16_t uint_least16_t; typedef uint32_t uint_least32_t; typedef uint64_t uint_least64_t; /* 7.18.1.3 Fastest-width integer types */ typedef int8_t int_fast8_t; typedef int16_t int_fast16_t; typedef int32_t int_fast32_t; typedef int64_t int_fast64_t; typedef uint8_t uint_fast8_t; typedef uint16_t uint_fast16_t; typedef uint32_t uint_fast32_t; typedef uint64_t uint_fast64_t; /* 7.18.1.4 Integer types capable of hgolding object pointers */ /* intptr_t is defined in <machine/types.h> */ /* uintptr_t is defined in <machine/types.h> */ /* 7.18.1.5 Greatest-width integer types */ typedef long long intmax_t; typedef unsigned long long uintmax_t; /* "C++ implementations should define these macros only when * __STDC_LIMIT_MACROS is defined before <stdint.h> is included." * In other words, if C++, then __STDC_LIMIT_MACROS enables the * macros below.
