iswgraph - test for graphic wide character

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-charac- ter 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 there- fore 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.

Notes

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