NAME    [Toc]    [Back]

       iswblank - test for whitespace wide character

SYNOPSIS    [Toc]    [Back]

       #include <wctype.h>

       int iswblank (wint_t wc);

DESCRIPTION    [Toc]    [Back]

       The  iswblank  function is the wide-character equivalent of the isblank
       function. It tests whether wc is a wide character belonging to the wide
       character class "blank".

       The  wide  character  class "blank" is a subclass of the wide character
       class "space".

       Being a subclass of the wide character class "space", the wide  character
 class "blank" is disjoint from the wide character class "graph" and
       therefore also disjoint from its subclasses "alnum", "alpha",  "upper",
       "lower", "digit", "xdigit", "punct".

       The  wide  character  class  "blank" always contains at least the space
       character and the control character '\t'.

RETURN VALUE    [Toc]    [Back]

       The iswblank function returns  non-zero	if  wc	is  a  wide  character
       belonging  to  the  wide  character class "blank". Otherwise it returns
       zero.

CONFORMING TO    [Toc]    [Back]

       This function is a GNU extension.

SEE ALSO    [Toc]    [Back]

      
      
       isblank(3), iswctype(3)

NOTES    [Toc]    [Back]

       The behaviour of iswblank depends on the LC_CTYPE category of the  current
 locale.
