Closes the COM library on the current thread, unloads all DLLs loaded by the thread, frees any other resources that the thread maintains, and forces all RPC connections on the thread to close.
void CoUninitialize( );
This function has no parameters.
This function does not return a value.
A thread must call CoUninitialize once for each successful call it has made to the CoInitialize or CoInitializeEx function, including any call that returns S_FALSE. Only the CoUninitialize call corresponding to the CoInitialize or CoInitializeEx call that initialized the library can close it.
Calls to OleInitialize must be balanced by calls to OleUninitialize. The OleUninitialize function calls CoUninitialize internally, so applications that call OleUninitialize do not also need to call CoUninitialize.
CoUninitialize should be called on application shutdown, as the last call made to the COM library after the application hides its main windows and falls through its main message loop. If there are open conversations remaining, CoUninitialize starts a modal message loop and dispatches any pending messages from the containers or server for this COM application. By dispatching the messages, CoUninitialize ensures that the application does not quit before receiving all of its pending messages. Non-COM messages are discarded.
