Upon completion, -.Fn aio_waitcomplete -returns the result of the function and sets -.Ar iocbp -to point to the structure associated with the original request. If an -asynchronous I/O request is completed before -.Fn aio_waitcomplete -is called, it returns immediately with the completed request. -.Pp -If -.Ar timeout -is a non-NULL pointer, it specifies a maximum interval to wait for a -asynchronous I/O request to complete. If -.Ar timeout -is a NULL pointer, -.Fn aio_waitcomplete -waits indefinitely. To effect a poll, the -.Ar timeout -argument should be non-NULL, pointing to a zero-valued timeval structure. -.Pp -The -.Fn aio_waitcomplete -function also serves the function of -.Fn aio_return , -thus -.Fn aio_return -should not be called for the control block returned in -.Ar iocbp . -.Sh RETURN VALUES -If an asynchronous I/O request has completed, -.Ar iocbp -is set to point to the control block passed with the original request, and -the status is returned as described in -.Xr read 2 , -.Xr write 2 , -or -.Xr fsync 2 . -On failure, -.Fn aio_waitcomplete -returns -.Dv -1 , -sets iocbp to -.Dv NULL -and -.Dv errno -to indicate the error condition. -.Sh ERRORS -The -.Fn aio_waitcomplete -function fails if: -.Bl -tag -width Er -.It Bq Er EINVAL -The specified time limit is invalid. -.It Bq Er EAGAIN -The process has not yet called -.Fn aio_read -or -.Fn aio_write . -.It Bq Er EINTR -A signal was delivered before the timeout expired and before any -asynchronous I/O requests completed. -.It Bq Er EWOULDBLOCK -.It Bq Er EINPROGRESS -The specified time limit expired before any asynchronous I/O requests -completed. -.El -.Sh SEE ALSO -.Xr aio_cancel 2 , -.Xr aio_error 2 , -.Xr aio_read 2 , -.Xr aio_return 2 , -.Xr aio_suspend 2 , -.Xr aio_write 2 , -.Xr fsync 2 , -.Xr read 2 , -.Xr write 2 . -.Sh STANDARDS -The -.Fn aio_waitcomplete -function is a FreeBSD-specific extension. -.Sh HISTORY -The -.Fn aio_waitcomplete -function first appeared in -.Fx 4.0 . -.Sh AUTHORS -The -.Fn aio_waitcomplete -function and this manual page were written by -.An Christopher M Sedore Aq cmsedore@maxwell.syr.edu . |
