NAME
iswspace - test for whitespace wide character SYNOPSIS
#include
int iswspace(wintt wc); DESCRIPTION The iswspace() function is the wide-character equivalent of the iss‐ pace(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 The iswspace() function returns nonzero if wc is a wide character
belonging to the wide-character class "space". Otherwise it returns zero. ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌───────────┬───────────────┬────────────────┐ │Interface │ Attribute │ Value │ ├───────────┼───────────────┼────────────────┤
