These are NOT the same as the 'C99 integer types' that are defined in the inttypes.h and stdint.h headers since attempts to use these types have shown that support for them is still highly variable. However, since the latter are of the form uint_t, a regular expression search and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t') can be used to convert the types used here to the C99 standard types. */ #ifndef _BRG_TYPES_H #define _BRG_TYPES_H #if defined(__cplusplus) extern "C" { #endif #include #include #if defined( _MSC_VER ) && ( _MSC_VER >= 1300 ) # include # define ptrint_t intptr_t #elif defined( __ECOS__ ) # define intptr_t unsigned int # define ptrint_t intptr_t #elif defined( __GNUC__ ) && ( __GNUC__ >= 3 ) # define ptrint_t intptr_t #else # define ptrint_t int #endif #ifndef BRG_UI32 # define BRG_UI32 # if UINT_MAX == 4294967295u # define li_32(h) 0x##h##u # elif ULONG_MAX == 4294967295u # define li_32(h) 0x##h##ul # elif defined( _CRAY ) # error This code needs 32-bit data types, which Cray machines do not provide # else # error Please define uint32_t as a 32-bit unsigned integer type in brg_types.h # endif #endif #ifndef BRG_UI64 # if defined( __BORLANDC__ ) && !defined( __MSDOS__ ) # define BRG_UI64 # define li_64(h) 0x##h##ui64 # elif defined( _MSC_VER ) && ( _MSC_VER < 1300 ) /* 1300 == VC++ 7.0 */ # define BRG_UI64 # define li_64(h) 0x##h##ui64 # elif defined( __sun ) && defined( ULONG_MAX ) && ULONG_MAX == 0xfffffffful # define BRG_UI64 # define li_64(h) 0x##h##ull # elif defined( __MVS__ ) # define BRG_UI64 # define li_64(h) 0x##h##ull # elif defined( UINT_MAX ) && UINT_MAX > 4294967295u # if UINT_MAX == 18446744073709551615u # define BRG_UI64 # define li_64(h) 0x##h##u # endif # elif defined( ULONG_MAX ) && ULONG_MAX > 4294967295u # if ULONG_MAX == 18446744073709551615ul # define BRG_UI64 # define li_64(h) 0x##h##ul # endif # elif defined( ULLONG_MAX ) && ULLONG_MAX > 4294967295u # if ULLONG_MAX == 18446744073709551615ull # define BRG_UI64 # define li_64(h) 0x##h##ull # endif # elif defined( ULONG_LONG_MAX ) && ULONG_LONG_MAX > 4294967295u # if ULONG_LONG_MAX == 18446744073709551615ull # define BRG_UI64 # define li_64(h) 0x##h##ull # endif # endif #endif #if !defined( BRG_UI64 ) # if defined( NEED_UINT_64T ) # error Please define uint64_t as an unsigned 64 bit type in brg_types.h # endif #endif #ifndef RETURN_VALUES # define RETURN_VALUES # if defined( DLL_EXPORT ) # if defined( _MSC_VER ) || defined ( __INTEL_COMPILER ) # define VOID_RETURN __declspec( dllexport ) void __stdcall # define INT_RETURN __declspec( dllexport ) int __stdcall # elif defined( __GNUC__ ) # define VOID_RETURN __declspec( __dllexport__ ) void # define INT_RETURN __declspec( __dllexport__ ) int # else # error Use of the DLL is only available on the Microsoft, Intel and GCC compilers # endif # elif defined( DLL_IMPORT ) # if defined( _MSC_VER ) || defined ( __INTEL_COMPILER ) # define VOID_RETURN __declspec( dllimport ) void __stdcall # define INT_RETURN __declspec( dllimport ) int __stdcall # elif defined( __GNUC__ ) # define VOID_RETURN __declspec( __dllimport__ ) void # define INT_RETURN __declspec( __dllimport__ ) int # else # error Use of the DLL is only available on the Microsoft, Intel and GCC compilers # endif # elif defined( __WATCOMC__ ) # define VOID_RETURN void __cdecl # define INT_RETURN int __cdecl # else # define VOID_RETURN void # define INT_RETURN int # endif #endif /* These defines are used to detect and set the memory alignment of pointers.
