* Name: aio_error
|
|
*
|
|
* Description:
|
|
* The aio_error() function returns the error status associated with the
|
|
* aiocb structure referenced by the aiocbp argument. The error status fo
|
|
* an asynchronous I/O operation is the errno value that would be set by
|
|
* the corresponding read(), write(), fdatasync(), or fsync() operation. If
|
|
* the operation has not yet completed, then the error status will be equal
|
|
* to EINPROGRESS.
|
|
*
|
|
* Input Parameters:
|
|
* aiocbp - A pointer to an instance of struct aiocb
|
|
*
|
|
* Returned Value:
|
|
* If the asynchronous I/O operation has completed successfully, then 0
|
|
* will be returned. If the asynchronous operation has completed
|
|
* unsuccessfully, then the error status, as described for read(),
|
|
* write(), fdatasync(), and fsync(), will be returned. If the
|
|
* asynchronous I/O operation has not yet completed, then EINPROGRESS will
|
|
* be returned.
|
|
*
|
|
* The aio_error() function may fail if:
|
|
*
|
|
* EINVAL - The aiocbp argument does not refer to an asynchronous
|
|
* operation whose return status has not yet been retrieved.
