тест на пробелы (test for whitespace wide character)

Имя (Name)

iswspace - test for whitespace wide character

Синопсис (Synopsis)

#include <wctype.h>

int iswspace(wint_t wc);


Описание (Description)

The iswspace() function is the wide-character equivalent of the
       isspace(3) function.  It tests whether wc is 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".

The wide-character class "space" always contains at least the space character and the control characters '\f', '\n', '\r', '\t', '\v'.


Возвращаемое значение (Return value)

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