Converting char to wchar_t.

[disanti]

Yes, I have Googled and Searched the forum for this.

I am reading a title from a file into a character array and now I want to set the window title but I can't... My current code puts a "??????????????????#0.02" into the caption:

wchar_t wtitle[128];
swprintf(wtitle, 128, L"%s%s", title, PSS4_VERSION);

If someone can please explain to me how to convert the character array title into a wide character array, that would be great! Thanks~ John DiSanti

Forgot to say: I did debug it and it is loading the text from the file flawlessly, the swprintf is the problem.

I think swprintf expects string arguments to be wide as well.

Search the http://www.gamedev.net forums. There's almost certainly something there.

The first search in google for "C++ converting char to wchar_t" pulls up several usuaful sites about using the wctob() function

here is one of them:

@thesmileman: That function is to convert a single byte wchar_t into a char... That is completely useless for my needs but thanks for looking!

what about this one:

_mbstowcsz(wchar_t* wcstr, const char* mbstr, size_t count);

That function appears to be Windows only, this is a Windows and Linux game.
