iswgraph − test for graphic wide character
Standard C library (libc, −lc)
#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.
