SYNOPSIS
#include <ctype.h>
int iswspace(
wint_t wc);
PARAMETER
wc Specifies a wide character for testing.
DESCRIPTION
This function tests a wide character wc for membership in the character class in the current
locale. If the wide character is part of the character class, the function returns a nonzero value
for true; otherwise, it returns a value of 0 (zero) for false.
The function returns a true value when wc is a character of class space in the program’s current
locale. At a minimum, the space, form-feed, newline, carriage-return, tab, and vertical-tab char-
acters are included in this class.
NOTES
This function determines the class of a wide character based on the LC_CTYPE locale category.
RETURN VALUES
If the wide character tested is part of the particular character class, this function returns a
nonzero value; otherwise it returns a value of 0 (zero).
ERRORS
None. This function does not set errno.
