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.
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.
