Added bool enum from machine/types.h for regular users * that want a real boolean type. * * 29-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University * Also change spacing of MAX and MIN to coincide with that of * sys/param.h. * * 19-Nov-85 Glenn Marcy (gm0w) at Carnegie-Mellon University * Changed the number of tabs between TRUE, FALSE and their * respective values to match those in sys/types.h. * * 17-Dec-84 Glenn Marcy (gm0w) at Carnegie-Mellon University * Only define TRUE and FALSE if not defined. Added caseE macro * for using enumerated types in switch statements. * * 23-Apr-81 Mike Accetta (mja) at Carnegie-Mellon University * Added "sizeofS" and "sizeofA" macros which expand to the size * of a string constant and array respectively. * ********************************************************************** */ #ifndef _C_INCLUDE_ #define _C_INCLUDE_ #ifndef ABS #define ABS(x) ((x)>=0?(x):-(x)) #endif /* ABS */ #ifndef MIN #define MIN(a,b) (((a)<(b))?(a):(b)) #endif /* MIN */ #ifndef MAX #define MAX(a,b) (((a)>(b))?(a):(b)) #endif /* MAX */ #ifndef FALSE #define FALSE 0 #endif /* FALSE */ #ifndef TRUE #define TRUE 1 #endif /* TRUE */ #define CERROR (-1) #ifndef bool typedef enum { false = 0, true = 1 } bool; #endif /* bool */ #define sizeofS(string) (sizeof(string) - 1) #define sizeofA(array) (sizeof(array)/sizeof(array[0])) #define caseE(enum_type) case (int)(enum_type) #endif /* _C_INCLUDE_ */
