ThreadPool.GetAvailableThreads Method (System.Threading)

.NET Framework Class Library

ThreadPool..::.GetAvailableThreads Method

Retrieves the difference between the maximum number of thread pool threads returned by the GetMaxThreads method, and the number currently active.

Namespace: System.Threading
Assembly: mscorlib (in mscorlib.dll)

Syntax

Public Shared Sub GetAvailableThreads ( _
	<OutAttribute> ByRef workerThreads As Integer, _
	<OutAttribute> ByRef completionPortThreads As Integer _
)

public static void GetAvailableThreads(
	out int workerThreads,
	out int completionPortThreads
)

public:
static void GetAvailableThreads(
	[OutAttribute] int% workerThreads, 
	[OutAttribute] int% completionPortThreads
)

static member GetAvailableThreads : 
        workerThreads:int byref * 
        completionPortThreads:int byref -> unit

Parameters

workerThreads: Type: System..::.Int32%
The number of available worker threads.

completionPortThreads: Type: System..::.Int32%
The number of available asynchronous I/O threads.

Remarks

When GetAvailableThreads returns, the variable specified by workerThreads contains the number of additional worker threads that can be started, and the variable specified by completionPortThreads contains the number of additional asynchronous I/O threads that can be started.

If there are no available threads, additional thread pool requests remain queued until thread pool threads become available.
