aio_error - get error status of asynchronous I/O operation
Návod, kniha: Linux Programmer's Manual
#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.
- EINVAL
- 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.
