Some ctype macros are valid only for character codes that isascii says are ASCII (SGI's IRIX-4.0.5 is one such system --when using /bin/cc or gcc but without giving an ansi option). So, all ctype uses should be through macros like ISPRINT... If STDC_HEADERS is defined, then autoconf has verified that the ctype macros don't need to be guarded with references to isascii. ... Defining isascii to 1 should let any compiler worth its salt eliminate the && through constant folding." Bruno Haible adds: "... Furthermore, isupper(c) etc. have an undefined result if c is outside the range -1 <= c <= 255. One is tempted to write isupper(c) with c being of type `char', but this is wrong if c is an 8-bit character >= 128 which gets sign-extended to a negative value. The macro ISUPPER protects against this as well." */ #if defined (STDC_HEADERS) || (!defined (isascii) && !defined (HAVE_ISASCII)) #define IN_CTYPE_DOMAIN(c) 1 #else #define IN_CTYPE_DOMAIN(c) isascii(c) #endif #ifdef isblank #define ISBLANK(c) (IN_CTYPE_DOMAIN (c) && isblank (c)) #else #define ISBLANK(c) ((c) == ' ' || (c) == '\t') #endif #ifdef isgraph #define ISGRAPH(c) (IN_CTYPE_DOMAIN (c) && isgraph (c)) #else #define ISGRAPH(c) (IN_CTYPE_DOMAIN (c) && isprint (c) && !isspace (c)) #endif #define ISPRINT(c) (IN_CTYPE_DOMAIN (c) && isprint (c)) #define ISALNUM(c) (IN_CTYPE_DOMAIN (c) && isalnum (c)) #define ISALPHA(c) (IN_CTYPE_DOMAIN (c) && isalpha (c)) #define ISCNTRL(c) (IN_CTYPE_DOMAIN (c) && iscntrl (c)) #define ISLOWER(c) (IN_CTYPE_DOMAIN (c) && islower (c)) #define ISPUNCT(c) (IN_CTYPE_DOMAIN (c) && ispunct (c)) #define ISSPACE(c) (IN_CTYPE_DOMAIN (c) && isspace (c)) #define ISUPPER(c) (IN_CTYPE_DOMAIN (c) && isupper (c)) #define ISXDIGIT(c) (IN_CTYPE_DOMAIN (c) && isxdigit (c)) #define ISDIGIT_LOCALE(c) (IN_CTYPE_DOMAIN (c) && isdigit (c)) /* ISDIGIT differs from ISDIGIT_LOCALE, as follows: - Its arg may be any int or unsigned int; it need not be an unsigned char. - It's guaranteed to evaluate its argument exactly once. - It's typically faster.
