function
<cwctype>

iswprint

int iswprint (wint_t c);
Check if wide character is printable
Checks whether c is a printable character.

A printable character is a character that occupies at least one printing position on a display (this is the opposite of a control character, checked with iswcntrl).

This function is the wide-character equivalent of isprint (<cctype>): If c translates with wctob to a character for which isprint is true, it is always considered a printable character by this function too.

In C++, a locale-specific template version of this function (isprint) exists in header <locale> for all character types.

Parameters

c
Wide character to be checked, casted to a wint_t, or WEOF.
wint_t is an integral type.

Return Value

A value different from zero (i.e., true) if indeed c is a printable character. Zero (i.e., false) otherwise.
