hi all!

im doing this:

int main(int in_argc, char **in_argv)
{
putenv(“SDL_VIDEODRIVER=windib”);

SDL_Init(SDL_INIT_VIDEO);

char l_driverName[16];
SDL_VideoDriverName(l_driverName, sizeof(l_driverName));
Trace("SDL Video Driver Name: %s\n", l_driverName);

…

driverName always return “directx”…

anything i m missing here?

thx

Hi,

I do this and it works:

 char envVariable[64];
 sprintf(envVariable,"SDL_VIDEODRIVER=windib");
 putenv(envVariable);

I’ve got different problem, but which is connected with yours… when I was using SDL 1.2.6 I always got “directx”, and asking for amount of available video card memory gave me good values that you would expect to get.

However, since I switched to SDL 1.2.8, I always get “windib”, and it’s more strange because I didn’t change even one line of code. Also, asking for amount of available video card memory gives me “0” in answer.

And what’s even more strange is that when I put:

putenv(“SDL_VIDEODRIVER=directx”)

before SDL_InitSubSystem(SDL_INIT_VIDEO), it always returns -1 (failed). I’m using WinXP, GeForce 4 MX… any ideas anyone?

Btw, is amount of available video card memory returned by SDL_GetVideoInfo() dynamic, ie. so I can call this function every frame and create realtime graphs how much textures take ATM? :slight_smile:

Are you using Visual Studio?

Try using _putenv() instead of putenv().

and launch from this windows your app
