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.
