These are NOT the same as the 'C99 integer types' that are 23 defined in the inttypes.h and stdint.h headers since attempts to use these 24 types have shown that support for them is still highly variable. However, 25 since the latter are of the form uint<nn>_t, a regular expression search 26 and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t') 27 can be used to convert the types used here to the C99 standard types. 28 */ 29 30 #ifndef _BRG_TYPES_H 31 #define _BRG_TYPES_H 32 33 #if defined(__cplusplus) 34 extern "C" { 35 #endif 36 37 #include <limits.h> 38 #include <stdint.h> 39 40 #if defined( _MSC_VER ) && ( _MSC_VER >= 1300 ) 41 # include <stddef.h> 42 # define ptrint_t intptr_t 43 #elif defined( __ECOS__ ) 44 # define intptr_t unsigned int 45 # define ptrint_t intptr_t 46 #elif defined( __GNUC__ ) && ( __GNUC__ >= 3 ) 47 # define ptrint_t intptr_t 48 #else 49 # define ptrint_t int 50 #endif 51 52 #ifndef BRG_UI32 53 # define BRG_UI32 54 # if UINT_MAX == 4294967295u 55 # define li_32(h) 0x##h##u 56 # elif ULONG_MAX == 4294967295u 57 # define li_32(h) 0x##h##ul 58 # elif defined( _CRAY ) 59 # error This code needs 32-bit data types, which Cray machines do not provide 60 # else 61 # error Please define uint32_t as a 32-bit unsigned integer type in brg_types.h 62 # endif 63 #endif 64 65 #ifndef BRG_UI64 66 # if defined( __BORLANDC__ ) && !defined( __MSDOS__ ) 67 # define BRG_UI64 68 # define li_64(h) 0x##h##ui64 69 # elif defined( _MSC_VER ) && ( _MSC_VER < 1300 ) /* 1300 == VC++ 7.0 */ 70 # define BRG_UI64 71 # define li_64(h) 0x##h##ui64 72 # elif defined( __sun ) && defined( ULONG_MAX ) && ULONG_MAX == 0xfffffffful 73 # define BRG_UI64 74 # define li_64(h) 0x##h##ull 75 # elif defined( __MVS__ ) 76 # define BRG_UI64 77 # define li_64(h) 0x##h##ull 78 # elif defined( UINT_MAX ) && UINT_MAX > 4294967295u 79 # if UINT_MAX == 18446744073709551615u 80 # define BRG_UI64 81 # define li_64(h) 0x##h##u 82 # endif 83 # elif defined( ULONG_MAX ) && ULONG_MAX > 4294967295u 84 # if ULONG_MAX == 18446744073709551615ul 85 # define BRG_UI64 86 # define li_64(h) 0x##h##ul 87 # endif 88 # elif defined( ULLONG_MAX ) && ULLONG_MAX > 4294967295u 89 # if ULLONG_MAX == 18446744073709551615ull 90 # define BRG_UI64 91 # define li_64(h) 0x##h##ull 92 # endif 93 # elif defined( ULONG_LONG_MAX ) && ULONG_LONG_MAX > 4294967295u 94 # if ULONG_LONG_MAX == 18446744073709551615ull 95 # define BRG_UI64 96 # define li_64(h) 0x##h##ull 97 # endif 98 # elif defined( UINT64_MAX ) && UINT64_MAX > 4294967295u 99 # if UINT64_MAX == __UINT64_C(18446744073709551615) 100 # define BRG_UI64 101 # define li_64(h) __UINT64_C(0x##h) 102 # endif 103 # endif 104 #endif 105 106 #if !defined( BRG_UI64 ) 107 # if defined( NEED_UINT_64T ) 108 # error Please define uint64_t as an unsigned 64 bit type in brg_types.h 109 # endif 110 #endif 111 112 #ifndef RETURN_VALUES 113 # define RETURN_VALUES 114 # if defined( DLL_EXPORT ) 115 # if defined( _MSC_VER ) || defined ( __INTEL_COMPILER ) 116 # define VOID_RETURN __declspec( dllexport ) void __stdcall 117 # define INT_RETURN __declspec( dllexport ) int __stdcall 118 # elif defined( __GNUC__ ) 119 # define VOID_RETURN __declspec( __dllexport__ ) void 120 # define INT_RETURN __declspec( __dllexport__ ) int 121 # else 122 # error Use of the DLL is only available on the Microsoft, Intel and GCC compilers 123 # endif 124 # elif defined( DLL_IMPORT ) 125 # if defined( _MSC_VER ) || defined ( __INTEL_COMPILER ) 126 # define VOID_RETURN __declspec( dllimport ) void __stdcall 127 # define INT_RETURN __declspec( dllimport ) int __stdcall 128 # elif defined( __GNUC__ ) 129 # define VOID_RETURN __declspec( __dllimport__ ) void 130 # define INT_RETURN __declspec( __dllimport__ ) int 131 # else 132 # error Use of the DLL is only available on the Microsoft, Intel and GCC compilers 133 # endif 134 # elif defined( __WATCOMC__ ) 135 # define VOID_RETURN void __cdecl 136 # define INT_RETURN int __cdecl 137 # else 138 # define VOID_RETURN void 139 # define INT_RETURN int 140 # endif 141 #endif 142 143 /* These defines are used to detect and set the memory alignment of pointers. 144 Note that offsets are in bytes. 145 146 ALIGN_OFFSET(x,n) return the positive or zero offset of 147 the memory addressed by the pointer 'x' 148 from an address that is aligned on an 149 'n' byte boundary ('n' is a power of 2) 150 151 ALIGN_FLOOR(x,n) return a pointer that points to memory 152 that is aligned on an 'n' byte boundary 153 and is not higher than the memory address 154 pointed to by 'x' ('n' is a power of 2) 155 156 ALIGN_CEIL(x,n) return a pointer that points to memory 157 that is aligned on an 'n' byte boundary 158 and is not lower than the memory address 159 pointed to by 'x' ('n' is a power of 2) 160 */ 161 162 #define ALIGN_OFFSET(x,n) (((ptrint_t)(x)) & ((n) - 1)) 163 #define ALIGN_FLOOR(x,n) ((uint8_t*)(x) - ( ((ptrint_t)(x)) & ((n) - 1))) 164 #define ALIGN_CEIL(x,n) ((uint8_t*)(x) + (-((ptrint_t)(x)) & ((n) - 1))) 165 166 /* These defines are used to declare buffers in a way that allows 167 faster operations on longer variables to be used.
