iswgraph - test for graphic wide character

  #include <wctype.h>

  int iswgraph(wint_t wc);

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”.

The *iswgraph*() function returns nonzero if wc is a wide character belonging to the wide-character class “graph”. Otherwise, it returns zero.

For an explanation of the terms used in this section, see *attributes*(7).

POSIX.1-2001, POSIX.1-2008, C99.

The behavior of iswgraph*() depends on the *LC_CTYPE category of the current locale.
