DispatchQueue(IntPtr)
Surfaces an unmanaged DispatchQueue as a managed object.
public DispatchQueue (IntPtr handle);new CoreFoundation.DispatchQueue : nativeint -> CoreFoundation.DispatchQueueParameters
- handle
-
IntPtr
nativeint
Handle to an unmanaged dispatch queue.
Applies to
DispatchQueue(String)
Creates a named dispatch queue that serializes all submitted blocks.
public DispatchQueue (string label);new CoreFoundation.DispatchQueue : string -> CoreFoundation.DispatchQueueParameters
- label
- String
Name for the dispatch queue, as a convention, use reverse-style DNS names for your queue name.
Remarks
Creates a dispatching queue that executes code blocks serially.
If you want to create a dispatch queue that can execute the submitted code concurrently, use the constructor that takes a boolean "concurrent" argument.
Applies to
DispatchQueue(String, Boolean)
Creates a named dispatch queue that can optionally execute any submitted code concurrently.
public DispatchQueue (string label, bool concurrent);new CoreFoundation.DispatchQueue : string * bool -> CoreFoundation.DispatchQueueParameters
- label
- String
Name for the dispatch queue, as a convention, use reverse-style DNS names for your queue name.
- concurrent
- Boolean
If set, the dispatch queue can invoke the submitted blocks concurrently.
Remarks
If the concurrent is set to false this is equivalent to calling the constructor tht takes a single string argument. That is, it will execute all submitted code blocks serially, one after another.
If the value is true then the queue can execute the code blocks concurrently. In this mode, you can use the DispatchBarrierAsync(Action) method to submit a code block that will wait for all pending concurrent blocks to complete execution, then it will execute the code block to completion. During the time that the barrier executes, any other code blocks submitted are queued, and will be scheduled to run (possibly concurrently) after the barrier method completes.
