NAME
aio_return - get return status of asynchronous I/O operation
SYNOPSIS
#include <aio.h>
ssize_t aio_return(struct aiocb *aiocbp);
Link with -lrt.
DESCRIPTION
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.
RETURN VALUE
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.
ERRORS
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.
CONFORMING TO
POSIX.1-2001.
