NAME    [Toc]    [Back]

       iswspace - test for whitespace wide character

SYNOPSIS    [Toc]    [Back]

       #include <wctype.h>

       int iswspace (wint_t wc);

DESCRIPTION    [Toc]    [Back]

       The  iswspace  function is the wide-character equivalent of the isspace
       function. It tests whether wc is a wide character belonging to the wide
       character class "space".

       The  wide  character  class "space" 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  "space"  contains the wide character class
       "blank".

       The wide character class "space" always contains  at  least  the  space
       character and the control characters '\f', '\n', '\r', '\t', '\v'.

RETURN VALUE    [Toc]    [Back]

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

CONFORMING TO    [Toc]    [Back]

       ISO/ANSI C, UNIX98

SEE ALSO    [Toc]    [Back]

      
      
       isspace(3), iswctype(3)

NOTES    [Toc]    [Back]

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