iswgraph - test for visible wide character

Syntax

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

Description iswgraph() tests whether the wide character specified by wc is a character with a visible

	representation, i.e. an alphanumeric or a special character. Spaces are not considered to be visible. 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	Character with a visible representation Not a character with a visible representation
Notes	iswgraph() 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 iswgraph). The behavior of iswgraph() is determined by the class graph 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)
