Stop Asynchronous Aio Operation

Source: R/aio.R
stop_aio.Rd

Stop an asynchronous Aio operation, or a list of Aio operations.

Usage

stop_aio(x)

Arguments

x

an Aio or list of Aios (objects of class ‘sendAio’, ‘recvAio’ or ‘ncurlAio’).

Value

Invisible NULL.

Details

Stops the asynchronous I/O operation associated with ‘aio’ by aborting, and then waits for it to complete or to be completely aborted, and for the callback associated with the ‘aio’ to have completed executing. If successful, the ‘aio’ will resolve to an ‘errorValue’ 20 (Operation canceled).

Note this function operates silently and does not error even if ‘aio’ is not an active Aio, always returning invisible NULL.
