ISWBLANK(3)                Linux Programmer's Manual               ISWBLANK(3)



NAME
       iswblank - test for whitespace wide character

SYNOPSIS
       #include <wctype.h>

       int iswblank(wint_t wc);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       iswblank():
              _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L

DESCRIPTION
       The  iswblank()  function  is  the  wide-character  equivalent  of  the
       isblank(3) 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-charac‐
       ter 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
       The iswblank() function returns nonzero  if  wc  is  a  wide  character
       belonging  to  the wide-character class "blank".  Otherwise, it returns
       zero.

CONFORMING TO

NOTES
       The behavior of iswblank() depends on the LC_CTYPE category of the cur‐
       rent locale.
