AIO_ERROR(3) |
NAME
aio_error - get error status of asynchronous I/O operation
SYNOPSIS
#include <aio.h>
int aio_error(const struct aiocb *
aiocbp
);
Link with
-lrt.
DESCRIPTION
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.)
RETURN VALUE
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 number, 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
fdatasync(2) call.
ERRORS
-
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.
-
ENOSYS
-
aio_error() is not implemented.

aio_error() function is available since glibc 2.1.
