#include <wctype.h> int iswgraph( wint_t wc );
- The wide character you want to test.

The iswgraph() function tests if the argument wc is a graphical wide character of the class graph. In the C locale, this class consists of all the printable characters, except the space character.
A nonzero value if the character is a member of the class graph, or 0 otherwise.
The result is valid only for wchar_t arguments and WEOF.
