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.

CONFORMING TO¶

C99.

NOTES¶

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

SEE ALSO¶
