aio_return — get return status of asynchronous I/O operation
#include <aio.h>
ssize_t aio_return( |
struct aiocb * | aiocbp); |
The aio_return() function
returns the final return status for the asynchronous I/O
request with control block pointed to by aiocbp.
This function should be called only once for any given request, after aio_error(3) returns something other than EINPROGRESS.
If the asynchronous I/O operation has completed, this
function returns the value that would have been returned in
case of a synchronous read,
write, or fsync request. Otherwise the return value
is undefined. On error, the error value is returned.
aiocbp does
not point at a control block for an asynchronous I/O
request of which the return status has not been
retrieved yet.
