Hello
I have a query about the ask about the aio_cancel description please.
http://man7.org/linux/man-pages/online/pages/man3/aio_cancel.3.html
"Normal asynchronous notification occurs for canceled requests. The request
return status is set to -1, and the request error status is set
to ECANCELED."
I would like to ask about this description. Could the detail of
"request return status" and "request error status" be described
please.
My assumption
"request return status" -- perhaps the value returned by aio_return()?
"request error status" -- not sure. maybe aio_error() ?
Thank you for taking a look into this.
Your assumption is correct. I added some words to the man page for
version 3.35 to clarify this.
Looks good.
Could I ask a related question. When an aio block is cancelled, is there
anyway to get back the byte count that was processed? e.g. aio_read, the
number of bytes read before the operation was cancelled.
Best regards, Jon
