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 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 non-zero if wc is a wide character belonging to the wide character class "graph". Otherwise it returns zero.
ISO/ANSI C, UNIX98
The behaviour of iswgraph depends on the LC_CTYPE category of the current locale.
