iswgraph(3)              Library Functions Manual             iswgraph(3)

NAME         top

       iswgraph - test for graphic wide character

LIBRARY         top

       Standard C library (libc, -lc)

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.

       current locale.
