aio_error — get error status of asynchronous I/O operation
#include <aio.h>
int
aio_error( |
const struct aiocb * | aiocbp) ; |
The aio_error
() function
returns the error status for the asynchronous I/O request
with control block pointed to by aiocbp
.
This function returns EINPROGRESS if the request has not
been completed yet. It returns ECANCELED if the request was
cancelled. It returns 0 if the request completed
successfully. Otherwise an error value is returned, the same
value that would have been stored in the errno
variable in case of a synchronous
read
, write
, fsync
,
or fdatasync
request. On error,
the error value is returned.
aiocbp
does
not point at a control block for an asynchronous I/O
request of which the return status (see aio_return(3)) has
not been retrieved yet.
