How to set Xfbdev background to transparent?

[vrushali shinde]

Hello All,
Could anyone tell me how to set Xfbdev bacground as transperent?
In InitRootWindow() function, I tried setting pWin->background.pixel =
0x0000FF00; //argb (a-00 r-00 g-ff b-00). This sets the background as green
and seems like the alpha is not used. Could anyone tell me the place in XOrg
to set Xfbdev background to transparent?
Thanks and Regards,
Vrushali
