31 * Demonstrate the waddwstr() and wadd_wch functions.
32 * Thomas Dickey - 2009/9/12
34 * Note: to provide inputs for *add_wch(), we use setcchar(). A quirk of the
35 * X/Open definition for that function is that the string contains no
36 * characters with negative width. Any control character (such as tab) falls
37 * into that category. So it follows that *add_wch() cannot render a tab
38 * character because there is no legal way to construct a cchar_t containing
39 * one. X/Open does not document this, and it would be logical to assume that
40 * *addwstr() has the same limitation, but it uses a wchar_t string directly,
41 * and does not document how tabs are handled.
44 #include <test.priv.h>
59 * redefinitions to simplify comparison between test_*str programs
