iswspace

Defined in header <wctype.h> 
int iswspace( wint_t ch );
-		 (since C95)

Checks if the given wide character is a whitespace character, i.e. either space (0x20), form feed (0x0c), line feed (0x0a), carriage return (0x0d), horizontal tab (0x09), vertical tab (0x0b) or any whitespace character specific to the current locale.

-

Parameters

- -
ch - wide character

Return value

Non-zero value if the wide character is a whitespace character, zero otherwise.

-

Notes

ISO 30112 defines POSIX space characters as Unicode characters U+0009..U+000D, U+0020, U+1680, U+180E, U+2000..U+2006, U+2008..U+200A, U+2028, U+2029, U+205F, and U+3000.

Example

#include <locale.h>
-#include <stdio.h>
-#include <wchar.h>
-#include <wctype.h>
- 
-int main(void)
-{
-    wchar_t c = L'\u2003'; // Unicode character 'EM SPACE'
-    printf("In the default locale, iswspace(%#x) = %d\n", c, !!iswspace(c));
-    setlocale(LC_ALL, "en_US.utf8");
-    printf("In Unicode locale, iswspace(%#x) = %d\n", c, !!iswspace(c));
-}

Output:

-
In the default locale, iswspace(0x2003) = 0
-In Unicode locale, iswspace(0x2003) = 1
