NAMEiswcntrl - test for control wide character
#include <wctype.h> int iswcntrl(wint_t wc);
DESCRIPTIONThe 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".
RETURN VALUEThe iswcntrl() function returns nonzero if wc is a wide character belonging to the wide-character class "cntrl". Otherwise it returns zero.
NOTESThe behavior of iswcntrl() depends on the LC_CTYPE category of the current locale.
