iswgraph — test for graphic wide character
iswgraph() function is
the wide-character equivalent of the isgraph(3) function. It
wc is a
wide character belonging to the wide-character class
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.
returns nonzero if
is a wide character belonging to the wide-character class
graph. Otherwise, it returns zero.
