aio_return - get return status of asynchronous I/O operation
#include <aio.h>
ssize_t aio_return(struct aiocb *aiocbp);
Link with -lrt.
The aio_return() function returns the final return status for the asynchronous
I/O request with control block pointed to by aiocbp. (See aio(7) for a
description of the aiocb structure.)
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(2),
write(2), fsync(2) or fdatasync(2), call.
If the asynchronous I/O operation has not yet completed, the return value and
effect of aio_return() are undefined.
EINVAL aiocbp does not point at a control block for an asynchronous I/O
request of which the return status has not been retrieved yet.
The aio_return() function is available since glibc 2.1.
POSIX.1-2001, POSIX.1-2008.
