ISWALNUM(3)						   BSD Library Functions Manual 					       ISWALNUM(3)

NAME

     iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph, iswlower, iswprint, iswpunct, iswspace, iswupper, iswxdigit -- wide character
     classification 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 sin-
     glebyte 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.

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <wctype.h>

     int
     iswalnum(wint_t wc);

     int
     iswalpha(wint_t wc);

     int

     iswspecial(wint_t wc);

     int
     iswupper(wint_t wc);

     int
     iswxdigit(wint_t wc);

DESCRIPTION

     The above functions are character classification utility functions, for use with wide characters (wchar_t or wint_t).  See the description
     for the similarly-named 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), isascii(3), isblank(3), iscntrl(3), isdigit(3), isgraph(3), ishexnumber(3), isideogram(3), islower(3), isnumber(3),
     isphonogram(3), isprint(3), ispunct(3), isrune(3), isspace(3), isspecial(3), isupper(3), isxdigit(3), wctype(3)

STANDARDS

     These functions conform to IEEE Std 1003.1-2001 (``POSIX.1''), except iswascii(), iswhexnumber(), iswideogram(), iswnumber(), iswphonogram(),
     iswrune() and iswspecial(), which are FreeBSD extensions.

CAVEATS

     The result of these functions is undefined unless the argument is WEOF or a valid wchar_t value for the current locale.
