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"#else/* 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 */};/* Character classification.  */extern const unsigned short _sch_istable[256];#define _sch_test(c, bit) (_sch_istable[(c) & 0xff] & (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_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 /* no ctype.h */#endif /* SAFE_CTYPE_H */
