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.
RETURN VALUE
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.
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.
CONFORMING TO
POSIX.1-2001.
