) -> CommandReturn
fn command( &self, command_num: usize, arg1: usize, _: usize, process_id: ProcessId ) -> CommandReturn
System call for a process to perform a short synchronous operation
or start a long-running split-phase operation (whose completion
is signaled with an upcall). Command 0 is a reserved command to
detect if a peripheral system call driver is installed and must
always return a CommandReturn::Success.

fn allocate_grant(&self, processid: ProcessId) -> Result<(), Error>

fn allow_userspace_readable( &self, app: ProcessId, which: usize, slice: ReadWriteProcessBuffer ) -> Result<ReadWriteProcessBuffer, (ReadWriteProcessBuffer, ErrorCode)>
System call for a process to pass a buffer (a
UserspaceReadableProcessBuffer
) to the kernel that the kernel can
either read or write. The kernel calls this method only after it checks
that the entire buffer is within memory the process can both read and
write. Read moreAuto Trait Implementations§
