Function Details : iswcntrl

Read about return values of iswcntrl function .

1st Parameter Type : wint_t

An integer type capable of storing any wide character value or the special value WEOF, used in wide-character input/output functions.

1st Parameter

The wide character to be tested, passed as a `wint_t`

The iswcntrlfunction in C language Checks whether the wide character is a control character.

The iswcntrl function tests whether wc is a wide character code representing a control character. Control characters are typically non-printing characters used to control the formatting or transmission of data.

The iswcntrlfunction takes 1 parameter:

•
wint_t `wc`: The wide character to be tested, passed as a `wint_t`

Checks if the given wide character `wc` is a control character. Control characters are non-printable characters such as wide newline (`\n`), wide tab (`\t`), and other wide characters in the control range. Returns a nonzero value if `wc` is a control character, and `0` otherwise.

The iswcntrl function return value :

Returns non-zero if the wide character is a control character, 0 otherwise

Output

This example demonstrates basic usage of iswcntrl with various wide characters.
