7 # AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
11 # the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
12 # existence of an include file <stdint.h> that defines a set of typedefs,
13 # especially uint8_t,int32_t,uintptr_t. Many older installations will not
14 # provide this file, but some will have the very same definitions in
15 # <inttypes.h>. In other environments we can use the inet-types in
16 # <sys/types.h> which would define the typedefs int8_t and u_int8_t
19 # This macros will create a local "_stdint.h" or the headerfile given as
20 # an argument. In many cases that file will just "#include <stdint.h>" or
21 # "#include <inttypes.h>", while in other environments it will provide the
22 # set of basic 'stdint's definitions/typedefs:
24 # int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
25 # int_least32_t.. int_fast32_t.. intmax_t
27 # which may or may not rely on the definitions of other files, or using
28 # the AC_CHECK_SIZEOF macro to determine the actual sizeof each type.
30 # if your header files require the stdint-types you will want to create an
31 # installable file mylib-int.h that all your other installable header may
32 # include. So if you have a library package named "mylib", just use
34 # AX_CREATE_STDINT_H(mylib-int.h)
36 # in configure.ac and go to install that very header file in Makefile.am
37 # along with the other headers (mylib.h) - and the mylib-specific headers
38 # can simply use "#include <mylib-int.h>" to obtain the stdint-types.
40 # Remember, if the system already had a valid <stdint.h>, the generated
41 # file will include it directly. No need for fuzzy HAVE_STDINT_H things...
42 # (oops, GCC 4.2.x has deliberately disabled its stdint.h for non-c99
43 # compilation and the c99-mode is not the default. Therefore this macro
44 # will not use the compiler's stdint.h - please complain to the GCC

528 * Use at your own risk. As of February 1996, the committee is squarely
529 * behind the fixed sized types; the "least" and "fast" types are still being
530 * discussed. The probability that the "fast" types may be removed before
531 * the standard is finalized is high enough that they are not currently
