To avoid conflicts, this header defines the isxxx functions in upper case, e.g. ISALPHA not isalpha. */ #ifndef SAFE_CTYPE_H #define SAFE_CTYPE_H #ifdef isalpha #error "safe-ctype.h and ctype.h may not be used simultaneously" #endif /* Determine host character set. */ #define HOST_CHARSET_UNKNOWN 0 #define HOST_CHARSET_ASCII 1 #define HOST_CHARSET_EBCDIC 2 #if '\n' == 0x0A && ' ' == 0x20 && '0' == 0x30 \ && 'A' == 0x41 && 'a' == 0x61 && '!' == 0x21 # define HOST_CHARSET HOST_CHARSET_ASCII #else # if '\n' == 0x15 && ' ' == 0x40 && '0' == 0xF0 \ && 'A' == 0xC1 && 'a' == 0x81 && '!' == 0x5A # define HOST_CHARSET HOST_CHARSET_EBCDIC # else # define HOST_CHARSET HOST_CHARSET_UNKNOWN # endif #endif /* Categories. */ enum { /* In C99 */ _sch_isblank = 0x0001, /* space \t */ _sch_iscntrl = 0x0002, /* nonprinting characters */ _sch_isdigit = 0x0004, /* 0-9 */ _sch_islower = 0x0008, /* a-z */ _sch_isprint = 0x0010, /* any printing character including ' ' */ _sch_ispunct = 0x0020, /* all punctuation */ _sch_isspace = 0x0040, /* space \t \n \r \f \v */ _sch_isupper = 0x0080, /* A-Z */ _sch_isxdigit = 0x0100, /* 0-9A-Fa-f */ /* Extra categories useful to cpplib. */ _sch_isidst = 0x0200, /* A-Za-z_ */ _sch_isvsp = 0x0400, /* \n \r */ _sch_isnvsp = 0x0800, /* space \t \f \v \0 */ /* Combinations of the above. */ _sch_isalpha = _sch_isupper|_sch_islower, /* A-Za-z */ _sch_isalnum = _sch_isalpha|_sch_isdigit, /* A-Za-z0-9 */ _sch_isidnum = _sch_isidst|_sch_isdigit, /* A-Za-z0-9_ */ _sch_isgraph = _sch_isalnum|_sch_ispunct, /* isprint and not space */ _sch_iscppsp = _sch_isvsp|_sch_isnvsp, /* isspace + \0 */ _sch_isbasic = _sch_isprint|_sch_iscppsp /* basic charset of ISO C (plus ` and @) */ }; /* Character classification. */ extern const unsigned short _sch_istable[256]; #define _sch_test(c, bit) (_sch_istable[(c) & 0xff] & (unsigned short)(bit)) #define ISALPHA(c) _sch_test(c, _sch_isalpha) #define ISALNUM(c) _sch_test(c, _sch_isalnum) #define ISBLANK(c) _sch_test(c, _sch_isblank) #define ISCNTRL(c) _sch_test(c, _sch_iscntrl) #define ISDIGIT(c) _sch_test(c, _sch_isdigit) #define ISGRAPH(c) _sch_test(c, _sch_isgraph) #define ISLOWER(c) _sch_test(c, _sch_islower) #define ISPRINT(c) _sch_test(c, _sch_isprint) #define ISPUNCT(c) _sch_test(c, _sch_ispunct) #define ISSPACE(c) _sch_test(c, _sch_isspace) #define ISUPPER(c) _sch_test(c, _sch_isupper) #define ISXDIGIT(c) _sch_test(c, _sch_isxdigit) #define ISIDNUM(c) _sch_test(c, _sch_isidnum) #define ISIDST(c) _sch_test(c, _sch_isidst) #define IS_ISOBASIC(c) _sch_test(c, _sch_isbasic) #define IS_VSPACE(c) _sch_test(c, _sch_isvsp) #define IS_NVSPACE(c) _sch_test(c, _sch_isnvsp) #define IS_SPACE_OR_NUL(c) _sch_test(c, _sch_iscppsp) /* Character transformation. */ extern const unsigned char _sch_toupper[256]; extern const unsigned char _sch_tolower[256]; #define TOUPPER(c) _sch_toupper[(c) & 0xff] #define TOLOWER(c) _sch_tolower[(c) & 0xff] #endif /* SAFE_CTYPE_H */
