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 39 #if defined( _MSC_VER ) && ( _MSC_VER >= 1300 ) 40 # include <stddef.h> 41 # define ptrint_t intptr_t 42 #elif defined( __ECOS__ ) 43 # define intptr_t unsigned int 44 # define ptrint_t intptr_t 45 #elif defined( __GNUC__ ) && ( __GNUC__ >= 3 ) 46 # include <stdint.h> 47 # define ptrint_t intptr_t 48 #else 49 # define ptrint_t int 50 #endif 51 52 #ifndef BRG_UI8 53 # define BRG_UI8 54 # if UCHAR_MAX == 255u 55 typedef unsigned char uint_8t;
