IDebugClient2::FlushCallbacks method (dbgeng.h)

The FlushCallbacks method forces any remaining buffered output to be delivered to the IDebugOutputCallbacks object registered with this client.

Syntax

HRESULT FlushCallbacks();

Return value

This method may also return error values. See Return Values for more details.

Remarks

The engine sometimes merges compatible callback requests to reduce callback overhead; small pieces of output are collected into larger groups to reduce the number of IDebugOutputCallbacks::Output calls. Using FlushCallbacks is necessary for a client to guarantee that all pending callbacks have been processed at a particular point. For example, a caller can flush callbacks before starting a lengthy operation outside of the engine so that pending callbacks are not delayed until after the operation.

For more information about callbacks, see Callbacks.
