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



NAME
       iswspace - test for whitespace wide character

SYNOPSIS
       #include <wctype.h>

       int iswspace(wint_t wc);

DESCRIPTION
       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
       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
       ISO/ANSI C, UNIX98

NOTES
       The  behaviour of iswspace depends on the LC_CTYPE category of the cur-
       rent locale.
