submit_job

Description:

[ Version ( since = "6.0" ) ]
public uint submit_job (MainContext? callback_context, owned WorkerFunc func, DestroyNotify? data_destroy_func) throws Error

Request that the worker thread call func with the data argument.

Notes: <itemizedlist> <listitem><para>if data_destroy_func is not null, then it will be called to destroy data when the job is removed, which can occur within the context of the worker thread, or within the context of any thread using this.</para></listitem> <listitem><para >if result_destroy_func is not null, then it will be called to destroy the result produced by func. Similarly to data_destroy_func, if it is not null (and if there is a non null result), then that function can be called in the context of any thread.</para ></listitem> <listitem><para>the error here can only report failures while executing submit_job , not any error which may occur while executing func from the worker thread.</para></listitem> < listitem><para>when this function returns, the job may already have been completed, so you should not assume that the job is in any specific state.</para></listitem> <listitem><para>passing null for callback_context is similar to passing the result of ref_thread_default</para>< /listitem> </itemizedlist>
