wctype -- get character class identifier by name LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wctype.h> wctype_t wctype(const char *charclass); DESCRIPTION
The wctype() function returns a character class identifier corresponding to the locale-specific character class name charclass. This identi- fier can be used in subsequent calls of iswctype(). The following names are defined in all locales: alnum alpha blank cntrl digit graph lower print punct space upper xdigit The behaviour of wctype() is affected by the LC_CTYPE category of the current locale. RETURN VALUES
wctype() returns: 0 If charclass does not correspond to a valid character class name. non-zero A character class identifier corresponding to charclass. Note: wctype_t is a scalar type, e.g., a pointer. ERRORS
No errors are defined. SEE ALSO
iswctype(3), setlocale(3), towctrans(3), wctrans(3) STANDARDS
The wctype() function conforms to ISO/IEC 9899/AMD1:1995 (``ISO C90, Amendment 1''). BSD

iswctype, iswctype_l, wctype, wctype_l -- wide character class functions LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <wctype.h> int iswctype(wint_t wc, wctype_t charclass); wctype_t wctype(const char *property); #include <wctype.h> #include <xlocale.h> int iswctype_l(wint_t wc, wctype_t charclass, locale_t loc); wctype_t wctype_l(const char *property, locale_t loc); DESCRIPTION
The wctype() function returns a value of type wctype_t, which represents the requested wide character class and may be used as the second argument for calls to iswctype(). The following character class names are recognised: alnum cntrl ideogram print space xdigit alpha digit lower punct special blank graph phonogram rune upper The iswctype() function checks whether the wide character wc is in the character class charclass. Although the iswctype() and wctype() functions use the current locale, the iswctype_l() and wctype_l() functions may be passed locales directly. See xlocale(3) for more information. RETURN VALUES
The iswctype() function returns non-zero if and only if wc has the property described by charclass, or charclass is zero. The wctype() function returns 0 if property is invalid; otherwise, it returns a value of type wctype_t that can be used in subsequent calls to iswctype(). EXAMPLES
Reimplement iswalpha(3) in terms of iswctype() and wctype(): int myiswalpha(wint_t wc) { return (iswctype(wc, wctype("alpha"))); } SEE ALSO
ctype(3), nextwctype(3), xlocale(3) STANDARDS
The iswctype() and wctype() functions conform to IEEE Std 1003.1-2001 (``POSIX.1''). The ``ideogram'', ``phonogram'', ``special'', and ``rune'' character classes are extensions. HISTORY
The iswctype() and wctype() functions first appeared in FreeBSD 5.0. BSD
