In this section
Topic | Description |
---|---|
File Buffering |
Describes considerations for application control of file buffering, also known as unbuffered file input/output (I/O). |
File Caching |
Windows caches file data that is read from disks and written to disks. |
Synchronous and Asynchronous I/O |
There are two types of input/output (I/O) synchronization: synchronous I/O and asynchronous I/O. Asynchronous I/O is also referred to as overlapped I/O. |
Canceling Pending I/O Operations |
Allowing users to cancel I/O requests that are slow or blocked can enhance the usability and robustness of your application. |
Alertable I/O |
Alertable I/O is the method by which application threads process asynchronous I/O requests only when they are in an alertable state. |
I/O Completion Ports |
I/O completion ports provide an efficient threading model for processing multiple asynchronous I/O requests on a multiprocessor system. |
