aio_error
—
retrieve error status of asynchronous I/O operation
(REALTIME)
Standard C Library (libc, -lc)
#include
<aio.h>
int
aio_error
(const struct aiocb
*aiocbp);
The
aio_error
()
system call returns the error status of the asynchronous I/O request
associated with the structure pointed to by
aiocbp.
If the asynchronous I/O request has completed successfully,
aio_error
() returns 0. If the request has not yet
completed, EINPROGRESS
is returned. If the request
has completed unsuccessfully, the error status is returned as described in
read(2),
write(2), or
fsync(2) is returned. On failure,
aio_error
() returns -1
and
sets errno
to indicate the error condition.
The aio_error
() system call will fail
if:
EINVAL
]aio_cancel(2), aio_read(2), aio_return(2), aio_suspend(2), aio_write(2), fsync(2), read(2), write(2), aio(4)
The aio_error
() system call is expected to
conform to the IEEE Std 1003.1
(“POSIX.1”) standard.
The aio_error
() system call first appeared
in FreeBSD 3.0.
