#include <windows.h>

char windir_name[] = &quot;c:\test.bmp&quot;;

SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, windir_name, SPIF_UPDATEINIFILE);

I don't know what's wrong with your code. Anyway, The following code works on my machine.

#include <windows.h>

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
::SystemParametersInfo(SPI_SETDESKWALLPAPER,
0,
(PVOID)lpCmdLine,
SPIF_UPDATEINIFILE);
return 0;
}
