NAME
aio_error - get error status of asynchronous I/O operation
LIBRARY
Real-time library
(librt, -lrt)
SYNOPSIS
#include <aio.h>
int aio_error(const struct aiocb *aiocbp);
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.
- > 0
-
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.
VERSIONS
The
aio_error()
function is available since glibc 2.1.
