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 canceled. 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.
