iswprint - test for printing wide character
#include <wctype.h>
int iswprint(wint_t wc);
The iswprint() function is the wide-character
equivalent of the isprint(3) function. It tests whether
wc
is a wide character belonging to the wide-character class
"print".
The wide-character class "print" is disjoint from the wide-character class "cntrl".
The wide-character class "print" contains the wide-character class "graph".
The iswprint() function returns nonzero if
wc
is a wide character belonging to the wide-character class
"print". Otherwise, it returns zero.
