/** @file | |
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. | |
