Description

Run .fio file in a separate process (child process)

process(file, args = [], on_updated = nothing, on_returned = nothing, on_finished = nothing)

Parameters

• file (string) — A .fio file to run (without .fio extension)
• args (array, optional) — Arguments to be passed to child process. Note: since the arguments will be packed as a JSON format, you cannot pass a "complex" object that refers to a memory address. For example: [gui_window(), gui_button()] will be passed as [nothing, nothing]. The default value is []
• on_updated (ref|function_call, optional) — A callback function to catch yielded data from the child process. The default value is nothing
• on_returned (ref|function_call, optional) — A callback function to catch returned data from the child process. The default value is nothing
• on_finished (ref|function_call, optional) — This function is called when the child process is finished running. The default value is nothing

Return Value

• boolean — Always returns true

Usage Example

import multiprocess
 
process("child", [10, "Hello"], nothing, nothing, process_finished())
 
function process_finished()
    writeln("A child process finished.")
stop
