iswspace - test for white-space wide character

Syntax

#include <wchar.h> int iswspace(wint_t wc);

Description iswspace() tests whether wc is a white-space wide character. White-space wide

	characters include: blanks, horizontal tabs, carriage returns, newlines, form-feeds, and vertical tabs. In all cases, wc is an argument of type wint_t, the value of which must be a wide character code corresponding to a valid character in the current locale or must equal the value of the macro WEOF. If the argument wc has any other value, the behavior is undefined.
Return val.	!= 0 0	White-space wide character Not a white-space wide character
Notes	iswspace() is implemented both as a function and as a macro. To generate a function call, the definition of the macro name must be first undefined (#undef iswspace). The behavior of iswspace() is determined by the class space of the current locale. The current locale is the C locale, unless it was explicitly changed using setlocale(). Restriction This version of the C runtime system only supports 1-byte characters as wide character codes. They are of type wchar_t (see stddef.h). (End)
