Gets the number of I/O completion threads, of the total number of threads managed by the host, that are not currently servicing requests.
[out] A pointer to the number of I/O completion threads managed by the host that are currently available to service requests.
GetAvailableThreads returned successfully.
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.
The call timed out.
The caller does not own the lock.
An event was canceled while a blocked thread or fiber was waiting on it.
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.
The host does not provide an implementation of GetAvailableThreads.
A host might want exclusive control over the size of the I/O completion thread pool, for reasons such as implementation, performance, or scalability. Therefore, the host is not required to implement GetAvailableThreads. In this case, the host should return E_NOTIMPL from this method.
