iswprint(3) Library Functions Manual iswprint(3)
iswprint - test for printing wide character
Standard C library (libc, -lc)
#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.
