The OCaml runtime is usually configurable via the OCAMLRUNPARAM
environment variable. We provide boot parameters covering these options.
--backtrace
: Output a backtrace if an uncaught exception terminated the unikernel.
The OCaml garbage collector can be configured, as described in detail in GC control.
The following Term.ts allow boot time configuration.
The initial delay, specified in seconds, before a unikernel starting up. Defaults to 0. Useful for tenders and environments that take some time to bring devices up.
at_exit hook
registers hook
, which will be executed before the unikernel exits. The first hook registered will be executed last.
at_enter_iter hook
registers hook
to be executed at the beginning of each event loop iteration. The first hook registered will be executed last.
If hook
calls at_enter_iter
recursively, the new hook will run only on the next event loop iteration.
at_leave_iter hook
registers hook
to be executed at the end of each event loop iteration. See at_enter_iter
for details.
This is mainly for for developers implementing new targets.
run_exit_hooks ()
calls the sequence of hooks registered with at_exit
in sequence.
run_enter_iter_hooks ()
calls the sequence of hooks registered with at_enter_iter
in sequence.
run_leave_iter_hooks ()
call the sequence of hooks registered with at_leave_iter
in sequence.
