pub unsafe fn register(
pd: &ProtectionDomain,
addr: *mut u8,
length: usize,
access_flags: AccessFlags,
metadata: T
) -> Result<Self>
Registers a memory region associated with the protection domain pd.
The memory region’s starting address is addr and its size is length.
Safety
- the memory region must be valid until it is deregistered
- the memory region must be initialized before it is read for the first time
