Function Details : iswblank

intiswblank(wint_t wc) ;

Read about return values of iswblank 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 iswblankfunction in C language Checks whether the wide character is a blank (space or tab).
The iswblank function tests whether wc is a wide character code representing a blank character. In many locales, this includes the space character and the horizontal tab.
The iswblankfunction 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 blank wide character (a space or a horizontal tab). Returns a nonzero value if `wc` is blank, and `0` otherwise.
The iswblank function return value :
  • Returns non-zero if the wide character is a blank character, 0 otherwise

Output

This example demonstrates basic usage of iswblank with various wide characters, including a wide space.
