Hi all, I am working on some project where I need to open Disk protocol. Below is my code-
Status = gBS->OpenProtocol(ControllerHandle
,&gEfiDiskIoProtocolGuid,(VOID **) &DiskIo, gImageHandle, NULL,
EFI_OPEN_PROTOCOL_BY_DRIVER);
if (EFI_ERROR(Status)) {
Print(L"Disk IO error %d\n",Status);
return Status;
}
Why this code always goes to error condition.
If I use EFI_OPEN_PROTOCOL_GET_PROTOCOL as parameter it will not go to error
condition, how to get rid of this problem ?
Best Regards,
Parmeshwr Prasad
