Constants
IORING_FEATURE_FLAGS_NONENone. |
IORING_FEATURE_UM_EMULATIONI/O ring support is emulated in User Mode. When this flag is set there is no underlying kernel support for I/O ring. However, a user mode emulation layer is available to provide application compatibility, without the benefit of kernel support. This provides application compatibility at the expense of performance, allowing apps to make a choice at run-time. As of the current release, Microsoft does not provide an emulated I/O ring implementation. This value is provided to support potential emulated future emulated implementations. |
IORING_FEATURE_SET_COMPLETION_EVENTRegistration of a completion queue event is supported. For more information, see SetIoRingCompletionEvent. |
