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_ #include <sys/cdefs.h> #include <sys/param.h> #ifndef FALSE #define FALSE 0 #endif /* FALSE */ #ifndef TRUE #define TRUE 1 #endif /* TRUE */ #ifndef MAX #define MAX(a,b) ((a)>(b)?(a):(b)) #endif #ifdef __arraycount #define sizeofA(array) __arraycount(array) #else #define sizeofA(array) (sizeof(array)/sizeof(array[0])) #endif #ifndef __unused #ifndef __GNUC__ #define __unused #else #define __unused __attribute__((__unused__)) #endif #endif #endif /* _C_INCLUDE_ */ |
