   iswgraph    ( 3 )

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.
