WCTYPE(3) FreeBSD Library Functions Manual WCTYPE(3)

iswctype, wctype
wide character class functions

Standard C Library (libc, -lc)

#include <wctype.h>
int
iswctype(wint_t wc, wctype_t charclass);
wctype_t
wctype(const char *property);

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:
cntrl ideogram print space xdigit
digit lower punct special
graph phonogram rune upper
The iswctype() function checks whether the wide character wc is in the character class charclass.

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().

Reimplement iswalpha(3) in terms of iswctype() and wctype():
int 
myiswalpha(wint_t wc) 
{ 
	return (iswctype(wc, wctype("alpha"))); 
}

ctype(3), nextwctype(3)

The iswctype() and wctype() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”). The “ideogram”, “phonogram”, “special”, and “rune” character classes are extensions.

The iswctype() and wctype() functions first appeared in FreeBSD 5.0.
March 27, 2004 FreeBSD 12.0-RELEASE
