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".
History
POSIX.1-2001, C99.
Library
Standard C library (libc, -lc)
Name
iswgraph - test for graphic wide character
Notes
The behavior of iswgraph() depends on the LC_CTYPE category of the current locale.
Return Value
The iswgraph() function returns nonzero if wc is a wide character belonging to the wide-character class
"graph". Otherwise, it returns zero.
