Exos.Proc (exos v2.0.0)
Link to this section Summary
Functions
Returns a specification to start this module under a supervisor.
Callback implementation for GenServer.init/1
.
Launch a GenServer which starts a port and proxify cast and call to
it using a port protocol with packet: 4
, (32bits-length+data)
messages are transmitted throught stdin/out. Input terms are
encoded using binary_to_term
and received terms are decoded using
term_to_binary
.

start_link(cmd, init, opts \\ [], link_opts \\ [], event_fun \\ nil)
Launch a GenServer which starts a port and proxify cast and call to
it using a port protocol with packet: 4
, (32bits-length+data)
messages are transmitted throught stdin/out. Input terms are
encoded using binary_to_term
and received terms are decoded using
term_to_binary
.
cmd
is the shell command to launch the port- when the port starts, it automatically receives as first message the
init
term ifinit !== :no_init
opts
are options forPort.open
(for instance[cd: "/path/"]
)link_opts
are options forGenServer.start_link
(for instance[name: :servername]
)- messages received from the port outside of a
GenServer.call
context trigger aevent_fun.(event)
call ifevent_fun
is notnil
(default) - to allow easy supervision, if the port die with a return code == 0, then
the GenServer die with the reason
:normal
, else with the reason:port_terminated
