1 office 1 dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
2 dnl
3 dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
4 dnl existence of an include file <stdint.h> that defines a set of
5 dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
6 dnl installations will not provide this file, but some will have the
7 dnl very same definitions in <inttypes.h>. In other enviroments we can
8 dnl use the inet-types in <sys/types.h> which would define the typedefs
9 dnl int8_t and u_int8_t respectivly.
10 dnl
11 dnl This macros will create a local "_stdint.h" or the headerfile given
12 dnl as an argument. In many cases that file will just "#include
13 dnl <stdint.h>" or "#include <inttypes.h>", while in other environments
14 dnl it will provide the set of basic 'stdint's definitions/typedefs:
15 dnl
16 dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
17 dnl int_least32_t.. int_fast32_t.. intmax_t
18 dnl
19 dnl which may or may not rely on the definitions of other files, or
20 dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
21 dnl type.
22 dnl
23 dnl if your header files require the stdint-types you will want to
24 dnl create an installable file mylib-int.h that all your other
25 dnl installable header may include. So if you have a library package
26 dnl named "mylib", just use
27 dnl
28 dnl AX_CREATE_STDINT_H(mylib-int.h)
29 dnl
30 dnl in configure.ac and go to install that very header file in
31 dnl Makefile.am along with the other headers (mylib.h) - and the
32 dnl mylib-specific headers can simply use "#include <mylib-int.h>" to
33 dnl obtain the stdint-types.
34 dnl
35 dnl Remember, if the system already had a valid <stdint.h>, the
36 dnl generated file will include it directly. No need for fuzzy
37 dnl HAVE_STDINT_H things...
