-Module Name:
-
- RtDevicePath.h
-
-Abstract:
-
- Device Path services. The thing to remember is device paths are built out of
- nodes. The device path is terminated by an end node that is length
- sizeof(EFI_DEVICE_PATH_PROTOCOL). That would be why there is sizeof(EFI_DEVICE_PATH_PROTOCOL)
- all over this file.
-
- The only place where multi-instance device paths are supported is in
- environment varibles. Multi-instance device paths should never be placed
- on a Handle.

-Routine Description:
- Function retrieves the next device path instance from a device path data structure.

- Size - A pointer to the size of a device path instance in bytes.
-
-Returns:
-
- This function returns a pointer to the current device path instance.
- In addition, it returns the size in bytes of the current device path instance in Size,
- and a pointer to the next device path instance in DevicePath.
- If there are no more device path instances in DevicePath, then DevicePath will be set to NULL.
