Use the C function to convert Unicode and ANSI text

Use the C function to convert Unicode and ANSI text

Char schar [max_path];
Const wchar [] = l "my friends ";
// Convert the Unicode string wchar to an ANSI string, save it to schar, and return the ANSI string size. If it fails,-1 is returned.
Wcstombs (schar, wchar, max_path );

In this case, the system always returns-1.

Later, I was reminded that you must set it before calling wcstombs.CodePage:

Char schar [max_path];
Const wchar [] = l "my friends ";

// Set the code page to the default code page
_ Tsetlocale (lc_all, _ T (""));
// Convert the Unicode string wchar to an ANSI string, save it to schar, and return the ANSI string size. If it fails,-1 is returned.
Wcstombs (schar, wchar, max_path );

That's all! No need to call annoying widechartomultibyte! Great!
Opposite functions:Mbstowcs, which can be converted from ANSI to Unicode
