NAME

       iswcntrl - test for control wide character

SYNOPSIS

       #include <wctype.h>

       int iswcntrl(wint_t wc);

DESCRIPTION

       The iswcntrl() function is the wide-character equivalent of the iscntrl(3) function.  It tests whether wc
       is a wide character belonging to the wide-character class "cntrl".

       The  wide-character  class  "cntrl"  is disjoint from the wide-character class "print" and therefore also
       disjoint from its subclasses "graph", "alpha", "upper", "lower", "digit", "xdigit", "punct".

       For an unsigned char c, iscntrl(c) implies iswcntrl(btowc(c)), but not vice versa.

RETURN VALUE

       The iswcntrl() function returns nonzero if wc is a wide character belonging to the  wide-character  class
       "cntrl".  Otherwise it returns zero.

CONFORMING TO

       C99.

NOTES

       The behavior of iswcntrl() depends on the LC_CTYPE category of the current locale.
