ISWPRINT(P)

NAME
iswprint - test for a printable wide-character code

SYNOPSIS

#include <wctype.h>

int iswprint(wint_t wc);

DESCRIPTION

The iswprint() function shall test whether wc is a wide-character code representing a character of class print in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale.

The wc argument is a wint_t, the value of which the application shall ensure is a wide-character code corresponding to a valid character in the current locale, or equal to the value of the macro WEOF. If the argument has any other value, the behavior is undefined.

RETURN VALUE

The iswprint() function shall return non-zero if wc is a printable wide-character code; otherwise, it shall return 0.
