тест на широкий графический символ (test for graphic wide character)
Имя (Name)
iswgraph - test for graphic wide character
Синопсис (Synopsis)
#include <wctype.h>
int iswgraph(wint_t wc);
Описание (Description)
The iswgraph() function is the wide-character equivalent of the
isgraph(3) function. It tests whether wc is a wide character
belonging to the wide-character class "graph".
The wide-character class "graph" is a subclass of the wide-
character class "print".
Being a subclass of the wide-character class "print", the wide-
character class "graph" is disjoint from the wide-character class
"cntrl".
The wide-character class "graph" is disjoint from the wide-
character class "space" and therefore also disjoint from its
subclass "blank".
The wide-character class "graph" contains all the wide characters
from the wide-character class "print" except the space character.
It therefore contains the wide-character classes "alnum" and
"punct".
Возвращаемое значение (Return value)
The iswgraph() function returns nonzero if wc is a wide character
belonging to the wide-character class "graph". Otherwise, it
returns zero.
