:description: Asynchronous I/O API reference for hipFile, covering stream-based non-blocking reads and writes and stream registration flags.

Asynchronous I/O API reference
|
|
*******************************
|
|
|
|
The hipFile asynchronous API lets you enqueue non-blocking reads and writes on
|
|
HIP streams. Stream registration communicates hints about fixed offsets and
|
|
alignment to the driver. On the AMD backend, asynchronous operations are
|
|
serviced through the fallback path rather than the fastpath.
|
|
|
|
For a step-by-step guide to using these functions, see
|
|
:doc:`/tutorials/async-multistream-io`.
|
|
|
|
Stream registration flags
|
|
===========================
|
|
|
|
Flags passed to ``hipFileStreamRegister`` to optimize stream processing when
|
|
transfer parameters are known at registration time.

Asynchronous I/O and stream registration functions
|
|
====================================================
|
|
|
|
Functions to enqueue non-blocking reads and writes on HIP streams and to
|
|
register and deregister streams with the hipFile driver.
