iswgraph — test for graphic wide character
#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 non-zero if wc
is a wide character
belonging to the wide-character class "graph". Otherwise it
returns zero.
The behaviour of iswgraph
()
depends on the LC_CTYPE category of the current locale.
