About this tag
The SetFileCompletionNotificationModes API is a Windows function that modifies how I/O completion port notifications are delivered. Based on forum discussions, this API can cause issues when used with non-IFS (Installable File System) Layered Service Providers (LSPs). Specifically, setting notification modes via this API may lead to I/O completion ports not working correctly with such LSPs. These threads highlight a compatibility problem where the API's behavior conflicts with certain network or file system filter drivers, potentially causing application failures or unexpected behavior in Windows environments. Developers and IT professionals should be aware of this limitation when implementing asynchronous I/O with completion ports and non-IFS LSPs.
