Hi,guys!
framebuffer->vtbl->GetAddress(framebuffer,&adr) always returns with
0x8000ffff ,it means
an unknow excption in xpcom.
i want to know why it could be this?
thanks a lot....
/////////////////////////////here is the code
IFramebuffer* framebuffer;
int xo,yo;
rc=display->vtbl->GetFramebuffer(display,0,&framebuffer,&xo,&yo);
if(NS_SUCCEEDED(rc)) printf("framebuffer exist\n");//realy exist...
unsigned int fw,fh,fbpp;
framebuffer->vtbl->GetWidth(framebuffer,&fw);
framebuffer->vtbl->GetHeight(framebuffer,&fh);
framebuffer->vtbl->GetBitsPerPixel(framebuffer,&fbpp);
printf("framebuffer Width: %u Height: %u Bits Per Pixel: %u \n ",fw,fh,bpp);
//printf outputs the correct Width Height and Bits Per Pixel......but
getaddress fails....
unsigned char* adr;
rc=framebuffer->vtbl->GetAddress(framebuffer,&adr);
if(NS_SUCCEEDED(rc)) ////////fails here ???why
printf(">>>>>>>>>>>>>>>>%p.......\n",adr);_______________________________________________
