aio_error - get error status of asynchronous I/O operation
#include <aio.h>
int aio_error(const struct aiocb *aiocbp);
Link with -lrt.
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.
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.
