iswctype()

Test a wide character to see if it's a given character class

Synopsis:

#include <wctype.h>

int iswctype( wint_t wc, 
              wctype_t charclass );

Arguments:

wc

The wide character you want to test.

charclass

The character class you want to test for. Get this class by calling wctype().

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The iswctype() function tests if the argument wc is a member of one or several character classes.

---

The results are unreliable if you didn't use wctype() to obtain charclass, or if a call to setlocale() affects LC_CTYPE.

---

Returns:

A nonzero value if the character is a member of the specified character class (or classes), or zero if the character isn't a member or charclass is 0.

Classification:

ANSI, POSIX 1003.1

Caveats:

The result is valid only for wchar_t arguments and WEOF.
