NAMEiswspace - test for whitespace wide character
#include <wctype.h>int iswspace(wint_t wc);
DESCRIPTIONThe iswspace() function is the wide-character equivalent of the isspace(3) function. It tests whether wcis a wide character belonging to the wide-character class "space".
The wide-character class "space" is disjoint from the wide-character class "graph" and therefore also disjoint from its subclasses "alnum", "alpha", "upper", "lower", "digit", "xdigit", "punct".
The wide-character class "space" contains the wide-character class "blank".
RETURN VALUEThe iswspace() function returns nonzero if wcis a wide character belonging to the wide-character class "space". Otherwise, it returns zero.
