Notifications for Process connections.
interface ref ProcessNotify
ProcessMonitor calls this when it is created.
fun ref created( process: ProcessMonitor ref) : None val
ProcessMonitor calls this when new data is received on STDOUT of the forked process
fun ref stdout( process: ProcessMonitor ref, data: Array[U8 val] iso) : None val
ProcessMonitor calls this when new data is received on STDERR of the forked process
fun ref stderr( process: ProcessMonitor ref, data: Array[U8 val] iso) : None val
ProcessMonitor calls this if we run into errors communicating with the forked process.
fun ref failed(
process: ProcessMonitor ref,
err: (ExecveError val | ForkError val | KillError val |
PipeError val | Unsupported val | WaitpidError val |
WriteError val | CapError val))
: None val
Called when the process monitor has been told to expect a certain quantity of bytes. This allows nested notifiers to change the expected quantity, which allows a lower level protocol to handle any framing.
fun ref expect( process: ProcessMonitor ref, qty: USize val) : USize val
Call when ProcessMonitor terminates to cleanup ProcessNotify. We return the exit code of the child process.
fun ref dispose( process: ProcessMonitor ref, child_exit_code: I32 val) : None val
