Method Details

run

@Deprecated
boolean run(IOSchedulerJob job,
 @Nullable Cancellable cancellable,
 @Nullable MemorySegment data)

Deprecated.

Use GLib.ThreadPool or Task.runInThread(TaskThreadFunc)

I/O Job function.

Long-running jobs should periodically check the cancellable to see if they have been cancelled.

Parameters:

job - a GIOSchedulerJob.

cancellable - optional GCancellable object, null to ignore.

data - data passed to the callback function

Returns:

true if this function should be called again to complete the job, false if the job is complete (or cancelled)

upcall

default int upcall(MemorySegment job,
 MemorySegment cancellable,
 MemorySegment data)

Deprecated.

The upcall method is called from native code. The parameters are marshaled and run(IOSchedulerJob, Cancellable, MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Deprecated.

Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated
