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



NAME
       iswgraph - test for graphic wide character

SYNOPSIS
       #include <wctype.h>

       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.

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