ISWGRAPH(3) Linux Programmers Manual ISWGRAPH(3)
NAME
iswgraph - test for graphic wide character
SYNOPSIS
#include
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-charac
ter 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 there
fore contains the wide-character classes "alnum" and "punct".
RETURN VALUE
The iswgraph() function returns non-zero 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 cur
rent locale.
