This may be useful if you have a better way - of determining the platform's endianness. The autoconf mechanism uses this for - example. - - A PA_VALIDATE_ENDIANNESS macro is provided to compare the compile time - and runtime endianness and raise an assertion if they don't match. -*/ - - -#ifdef __cplusplus -extern "C" -{ -#endif /* __cplusplus */ - -/* If this is an apple, we need to do detect endianness this way */ -#if defined(__APPLE__) - /* we need to do some endian detection that is sensitive to hardware arch */ - #if defined(__LITTLE_ENDIAN__) - #if !defined( PA_LITTLE_ENDIAN ) - #define PA_LITTLE_ENDIAN - #endif - #if defined( PA_BIG_ENDIAN ) - #undef PA_BIG_ENDIAN - #endif - #else - #if !defined( PA_BIG_ENDIAN ) - #define PA_BIG_ENDIAN - #endif - #if defined( PA_LITTLE_ENDIAN ) - #undef PA_LITTLE_ENDIAN - #endif - #endif -#else - /* this is not an apple, so first check the existing defines, and, failing that, - detect well-known architectures. */ - - #if defined(PA_LITTLE_ENDIAN) || defined(PA_BIG_ENDIAN) - /* endianness define has been set externally, such as by autoconf */ - - #if defined(PA_LITTLE_ENDIAN) && defined(PA_BIG_ENDIAN) - #error both PA_LITTLE_ENDIAN and PA_BIG_ENDIAN have been defined externally to pa_endianness.h - only one endianness at a time please - #endif - - #else - /* endianness define has not been set externally */ - - /* set PA_LITTLE_ENDIAN or PA_BIG_ENDIAN by testing well known platform specific defines */ - - #if defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(__NT__) || defined(LITTLE_ENDIAN) || defined(__i386) || defined(_M_IX86) || defined(__x86_64__) - #define PA_LITTLE_ENDIAN /* win32, assume intel byte order */ - #else - #define PA_BIG_ENDIAN - #endif - #endif - - #if !defined(PA_LITTLE_ENDIAN) && !defined(PA_BIG_ENDIAN) - /* - If the following error is raised, you either need to modify the code above - to automatically determine the endianness from other symbols defined on your - platform, or define either PA_LITTLE_ENDIAN or PA_BIG_ENDIAN externally. - */ - #error pa_endianness.h was unable to automatically determine the endianness of the target platform - #endif - -#endif - - -/* PA_VALIDATE_ENDIANNESS compares the compile time and runtime endianness, - and raises an assertion if they don't match. <assert.h> must be included in - the context in which this macro is used. -*/ -#if defined(NDEBUG) - #define PA_VALIDATE_ENDIANNESS -#else - #if defined(PA_LITTLE_ENDIAN) - #define PA_VALIDATE_ENDIANNESS \ - { \ - const long nativeOne = 1; \ - assert( "PortAudio: compile time and runtime endianness don't match" && (((char *)&nativeOne)[0]) == 1 ); \ - } - #elif defined(PA_BIG_ENDIAN) - #define PA_VALIDATE_ENDIANNESS \ - { \ - const long nativeOne = 1; \ - assert( "PortAudio: compile time and runtime endianness don't match" && (((char *)&nativeOne)[0]) == 0 ); \ - } - #endif -#endif - - -#ifdef __cplusplus -} -#endif /* __cplusplus */ -#endif /* PA_ENDIANNESS_H */ |
