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

NAME         top

       iswspace - test for whitespace wide character

SYNOPSIS         top

       #include <wctype.h>

       int iswspace(wint_t wc);

DESCRIPTION         top

       The iswspace() function is the wide-character equivalent of the isspace(3)
       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         top

       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         top

       C99.

NOTES         top

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