aio_error - get error status of asynchronous I/O operation
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. (See aio(7) for a
description of the aiocb structure.)
This function returns one of the following:
* EINPROGRESS, if the request has not been completed yet.
* ECANCELED, if the request was canceled.
* 0, if the request completed successfully.
* A positive error, if the asynchronous I/O operation failed. This is
the same value that would have been stored in the errno variable in
the case of a synchronous read(2), write(2), fsync(2), or
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.
The aio_error() function is available since glibc 2.1.
