IHostThreadPoolManager::SetMaxThreads Method

Sets the maximum number of threads that the host can maintain in the thread pool.

HRESULT SetMaxThreads (
    [in] DWORD MaxThreads
);

MaxThreads

The maximum number of worker threads in the thread pool.

HRESULT

Description

S_OK

SetMaxThreads returned successfully.

HOST_E_CLRNOTAVAILABLE

The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.

HOST_E_TIMEOUT

The call timed out.

HOST_E_NOT_OWNER

The caller does not own the lock.

HOST_E_ABANDONED

An event was canceled while a blocked thread or fiber was waiting on it.

E_FAIL

An unknown, catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

E_NOTIMPL

The host does not provide an implementation of SetMaxThreads.

A host is not required to allow the CLR to configure the size of the thread pool. Some hosts might want exclusive control over the thread pool, for reasons such as implementation, performance, or scalability. In this case, a host should return an HRESULT value of E_NOTIMPL.
