The following values are guaranteed to be recognized: "alnum", "alpha", "blank", "cntrl", "digit", "graph", "lower", "print", "punct", "space", "upper", and "xdigit". RETURNS <<wctype>> returns 0 and sets <<errno>> to <<EINVAL>> if the given name is invalid. Otherwise, it returns a valid non-zero wctype_t value. PORTABILITY <<wctype>> is C99. No supporting OS subroutines are required. */ #include <_ansi.h> #include <string.h> #include <reent.h> #include <wctype.h> #include <errno.h> #include "local.h" wctype_t _DEFUN (_wctype_r, (r, c), struct _reent *r _AND const char *c) { switch (*c) { case 'a': if (!strcmp (c, "alnum")) return WC_ALNUM; else if (!strcmp (c, "alpha")) return WC_ALPHA; break; case 'b': if (!strcmp (c, "blank")) return WC_BLANK; break; case 'c': if (!strcmp (c, "cntrl")) return WC_CNTRL; break; case 'd': if (!strcmp (c, "digit")) return WC_DIGIT; break; case 'g': if (!strcmp (c, "graph")) return WC_GRAPH; break; case 'l': if (!strcmp (c, "lower")) return WC_LOWER; break; case 'p': if (!strcmp (c, "print")) return WC_PRINT; else if (!strcmp (c, "punct")) return WC_PUNCT; break; case 's': if (!strcmp (c, "space")) return WC_SPACE; break; case 'u': if (!strcmp (c, "upper")) return WC_UPPER; break; case 'x': if (!strcmp (c, "xdigit")) return WC_XDIGIT; break; } /* otherwise invalid */ r->_errno = EINVAL; return 0; } #ifndef _REENT_ONLY wctype_t _DEFUN (wctype, (c), const char *c) { return _wctype_r (_REENT, c); } #endif /* !_REENT_ONLY */
