NAME¶iswgraph - test for graphic wide character
#include <wctype.h> int iswgraph(wint_t wc);
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".
RETURN VALUE¶The iswgraph() function returns nonzero if wc is a wide character belonging to the wide-character class "graph". Otherwise, it returns zero.
ATTRIBUTES¶For an explanation of the terms used in this section, see attributes(7).
