iswprint - Test for printing wide character

Definition	#include <wctype.h> int iswprint(wint_t wc); iswprint tests whether wc is a printing wide character. Printing wide characters include alphanumeric characters, special characters, and blanks. 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	wc is a printing wide character (alphanumeric characters, special characters, and blanks).
	0	wc is not a printing wide character.
Notes	This version of the C runtime system only supports one-byte characters as wide character codes. iswprint is implemented both as a function and as a macro (see section “Functions and macros”). The behavior of iswprint is determined by the class print of the current locale. The current locale is the C locale, unless it was explicitly changed using setlocale.
