But today more important is that - the arrays are also used for multi-byte character sets. */ -extern const unsigned short int **__ctype_b_loc (void) - __THROW __attribute__ ((__const__)); -extern const __int32_t **__ctype_tolower_loc (void) - __THROW __attribute__ ((__const__)); -extern const __int32_t **__ctype_toupper_loc (void) - __THROW __attribute__ ((__const__)); - - -#ifndef __cplusplus -# define __isctype(c, type) \ - ((*__ctype_b_loc ())[(int) (c)] & (unsigned short int) type) -#elif defined __USE_EXTERN_INLINES -# define __isctype_f(type) \ - __extern_inline int \ - is##type (int __c) __THROW \ - { \ - return (*__ctype_b_loc ())[(int) (__c)] & (unsigned short int) _IS##type; \ - } -#endif - -#define __isascii(c) (((c) & ~0x7f) == 0) /* If C is a 7 bit value. */ -#define __toascii(c) ((c) & 0x7f) /* Mask off high bits. */ - -#define __exctype(name) extern int name (int) __THROW - -/* The following names are all functions: - int isCHARACTERISTIC(int c); - which return nonzero iff C has CHARACTERISTIC. - For the meaning of the characteristic names, see the `enum' above. */ -__exctype (isalnum); -__exctype (isalpha); -__exctype (iscntrl); -__exctype (isdigit); -__exctype (islower); -__exctype (isgraph); -__exctype (isprint); -__exctype (ispunct); -__exctype (isspace); -__exctype (isupper); -__exctype (isxdigit); - - -/* Return the lowercase version of C. */ -extern int tolower (int __c) __THROW; - -/* Return the uppercase version of C. */ -extern int toupper (int __c) __THROW; - - -/* ISO C99 introduced one new function. */ -#ifdef __USE_ISOC99 -__exctype (isblank); -#endif - -#ifdef __USE_GNU -/* Test C for a set of character classes according to MASK. */ -extern int isctype (int __c, int __mask) __THROW; -#endif - -#if defined __USE_MISC || defined __USE_XOPEN - -/* Return nonzero iff C is in the ASCII set - (i.e., is no more than 7 bits wide). */ -extern int isascii (int __c) __THROW; - -/* Return the part of C that is in the ASCII set - (i.e., the low-order 7 bits of C). */ -extern int toascii (int __c) __THROW; - -/* These are the same as `toupper' and `tolower' except that they do not - check the argument for being in the range of a `char'. */ -__exctype (_toupper); -__exctype (_tolower); -#endif /* Use X/Open or use misc. */ - -/* This code is needed for the optimized mapping functions. */ -#define __tobody(c, f, a, args) \ - (__extension__ \ - ({ int __res; \ - if (sizeof (c) > 1) \ - { \ - if (__builtin_constant_p (c)) \ - { \ - int __c = (c); \ - __res = __c < -128 || __c > 255 ? __c : (a)[__c]; \ - } \ - else \ - __res = f args; \ - } \ - else \ - __res = (a)[(int) (c)]; \ - __res; })) - -#if !defined __NO_CTYPE -# ifdef __isctype_f -__isctype_f (alnum) -__isctype_f (alpha) -__isctype_f (cntrl) -__isctype_f (digit) -__isctype_f (lower) -__isctype_f (graph) -__isctype_f (print) -__isctype_f (punct) -__isctype_f (space) -__isctype_f (upper) -__isctype_f (xdigit) -# ifdef __USE_ISOC99 -__isctype_f (blank) -# endif -# elif defined __isctype -# define isalnum(c) __isctype((c), _ISalnum) -# define isalpha(c) __isctype((c), _ISalpha) -# define iscntrl(c) __isctype((c), _IScntrl) -# define isdigit(c) __isctype((c), _ISdigit) -# define islower(c) __isctype((c), _ISlower) -# define isgraph(c) __isctype((c), _ISgraph) -# define isprint(c) __isctype((c), _ISprint) -# define ispunct(c) __isctype((c), _ISpunct) -# define isspace(c) __isctype((c), _ISspace) -# define isupper(c) __isctype((c), _ISupper) -# define isxdigit(c) __isctype((c), _ISxdigit) -# ifdef __USE_ISOC99 -# define isblank(c) __isctype((c), _ISblank) -# endif -# endif - -# ifdef __USE_EXTERN_INLINES -__extern_inline int -__NTH (tolower (int __c)) -{ - return __c >= -128 && __c < 256 ?
