Example
HRESULT DoPoolOperations(IThreadPoolConfig* pPool, int nSize)
{
int nCurrSize = 0;
HRESULT hr = pPool->GetSize(&nCurrSize);
if (SUCCEEDED(hr))
{
printf_s("Current pool size: %d\n", nCurrSize);
hr = pPool->SetSize(nSize);
if (SUCCEEDED(hr))
{
printf_s("New pool size : %d\n", nSize);
DWORD dwTimeout = 0;
hr = pPool->GetTimeout(&dwTimeout);
if (SUCCEEDED(hr))
{
printf_s("Current pool timeout: %u\n", dwTimeout);
// Increase timeout by 10 seconds.
dwTimeout += 10 * 1000;
hr = pPool->SetTimeout(dwTimeout);
if (SUCCEEDED(hr))
{
printf_s("New pool timeout: %u\n", dwTimeout);
}
else
