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 STDC_HEADERS || (!defined (isascii) && !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 /* This is defined in on at least Solaris2.6 systems. */ #undef ISPRINT #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)) #if STDC_HEADERS # define TOLOWER(Ch) tolower (Ch) # define TOUPPER(Ch) toupper (Ch) #else # define TOLOWER(Ch) (ISUPPER (Ch) ? tolower (Ch) : (Ch)) # define TOUPPER(Ch) (ISLOWER (Ch) ? toupper (Ch) : (Ch)) #endif /* 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.
