iswgraph(3) Library Functions Manual iswgraph(3) NAME iswgraph - test for graphic wide character LIBRARY Standard C library (libc, -lc) SYNOPSIS #include 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.
