NAME¶aio_return — retrieve return status of asynchronous I/O operation (REALTIME)
LIBRARY¶Standard C Library (libc, -lc)
SYNOPSIS¶#include <aio.h> int
aio_return(struct aiocb *iocb);
DESCRIPTION¶The aio_return() system call returns the final status of the asynchronous I/O request associated with the structure pointed to by iocb. The aio_return() system call should only be called once, to obtain the final status of an asynchronous I/O operation once it has completed (aio_error(2) returns something other than
RETURN VALUES¶If the asynchronous I/O request has completed, the status is returned as described in read(2), write(2), or fsync(2). Otherwise, aio_return() returns -1 and sets errno to indicate the error condition.
ERRORS¶The aio_return() system call will fail if:
- The iocb argument does not reference a completed asynchronous I/O request.
SEE ALSO¶aio_cancel(2), aio_error(2), aio_suspend(2), aio_waitcomplete(2), aio_write(2), fsync(2), read(2), write(2), aio(4)
STANDARDS¶The aio_return() system call is expected to conform to the IEEE Std 1003.1 (“POSIX.1”) standard.
