NAME

     iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph, iswlower,
     iswprint, iswpunct, iswspace, iswupper, iswxdigit -- wide character clas-
     sification utilities


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <wctype.h>

     int
     iswalnum(wint_t wc);

     int
     iswalpha(wint_t wc);

     int
     iswblank(wint_t wc);

     int
     iswcntrl(wint_t wc);

     int
     iswdigit(wint_t wc);

     int
     iswgraph(wint_t wc);

     int
     iswlower(wint_t wc);

     int
     iswprint(wint_t wc);

     int
     iswpunct(wint_t wc);

     int
     iswspace(wint_t wc);

     int
     iswupper(wint_t wc);

     int
     iswxdigit(wint_t wc);


DESCRIPTION

     The functions are character classification utility functions, for use
     with wide characters (wchar_t or wint_t).  See the description of single-
     byte classification functions, like isalnum(3), for details.


RETURN VALUES

     The functions return zero if the character tests false and return non-
     zero if the character tests true.


SEE ALSO

     isalnum(3), isalpha(3), isblank(3), iscntrl(3), isdigit(3), isgraph(3),
     islower(3), isprint(3), ispunct(3), isspace(3), isupper(3), isxdigit(3)


STANDARDS

     The functions conform to ISO/IEC 9899:1999 (``ISO C99'').


CAVEATS

     The argument to these functions must be WEOF or a valid wchar_t value
     with the current locale; otherwise, the result is undefined.
