Abort

Declaration

virtual kern_return_t Abort(IOOptionBits options, kern_return_t withError, IOService *forClient);

Parameters

• options:

  Options for how to abort the requests. For a list of possible values, see Iousbabortoptions.

• withError:

  The error value to report for each request. Specify kIOReturnAborted for this parameter.

• forClient:

  The service that initiated the requests. Specify a non NULL value for this parameter only for pipes associated with a control endpoint; specify NULL for other endpoint types. For a control endpoint, you can also specify NULL to abort all requests.

Return Value

kIOReturnSuccess on success, or another value if an error occurs. See Error Codes.

Discussion

If the options argument includes kAbortSynchronous, this method blocks all new I/O requests except those submitted by an aborted completion routine.
