Section (3) iswgraph


Linux manual pages Section 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.
