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 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. CONFORMING TO C99. NOTES The behavior of iswspace() depends on the LC_CTYPE category of the cur- rent locale. SEE ALSO isspace(3), iswctype(3) COLOPHON This page is part of release 3.27 of the Linux man-pages project.
