ISWGRAPH(3)               Linux Programmer's Manual              ISWGRAPH(3)

NAME         top

       iswgraph - test for graphic wide character

SYNOPSIS         top

       #include <wctype.h>
       int iswgraph(wint_t wc);

DESCRIPTION         top

       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         top

       The iswgraph() function returns nonzero if wc is a wide character
       belonging to the wide-character class "graph".  Otherwise, it returns
       zero.

NOTES         top

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