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(3) function.  It tests whether wc is a wide char-
       acter 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 nonzero if wc is a wide character belonging to the wide-character class "space".   Other-
       wise it returns zero.

CONFORMING TO
       C99.

NOTES
       The behavior of iswspace() depends on the LC_CTYPE category of the current locale.
