-.SH NAME
-iswspace \- test for whitespace wide character
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.B #include <wctype.h>
-.P
-.BI "int iswspace(wint_t " wc );
-.fi
-.SH DESCRIPTION
-The
-.BR iswspace ()
-function is the wide-character equivalent of the
-.BR isspace (3)
-function.
-It tests whether
-.I wc
-is a wide character
-belonging to the wide-character class "space".
-.P
-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".
-.\" Note: UNIX98 (susv2/xbd/locale.html) says that "space" and "graph" may
-.\" have characters in common, except U+0020. But C99 (ISO/IEC 9899:1999
-.\" section 7.25.2.1.10) says that "space" and "graph" are disjoint.
-.P
-The wide-character class "space" contains the wide-character class "blank".
-.P
-The wide-character class "space"
-always contains at least the space character
-and the control characters
-\[aq]\ef\[aq], \[aq]\en\[aq], \[aq]\er\[aq], \[aq]\et\[aq], and \[aq]\ev\[aq].
-.SH RETURN VALUE
-The
-.BR iswspace ()
-function returns nonzero if
-.I wc
-is a wide character
-belonging to the wide-character class "space".
-Otherwise, it returns zero.
