I don't have first hand experience with SVR4 yet, though I have access to all the manuals that Prentice-Hall sells. I have heard various rumblings that asynchronous I/O was in the SVR4 design documents distributed some time ago. I can't find anything in the manuals about any type of asynchronous I/O support. But today a friend told me about all sorts of asynchronous I/O functions mentioned in standard header files in SVR4, in particular: /usr/include/sys/asyncio.h /usr/include/sys/asyncsys.h hints of an async(2) system call, an aiodaemon, an aioinit function lots of defines for AIOxxx symbols mention that this is Version 2, and Version 1 was a prototype Does anyone know the story? It would be best if AT&T stepped forward and spilled the beans, but, in the best traditions of Usenet, rumors and innuendo are welcome, too. :-) Even something from AT&T along the lines of "Sure it exists but if we told you about it, we would have to kill you." would be okay. Maybe only large application vendors get the details. :-( -- A. Lester Buck buck@siswat.lonestar.org ...!uhnix1!lobster!siswat!buck

How about everyone with a Sun? SunOS 4.1 (billed as Sun's transition
to SVR4) includes all of <sys/asynch.h>, aiocancel(3), aioread(3),
aiowait(3), and aiowrite(3).guy@auspex.auspex.com (Guy Harris) (12/07/90)
>How about everyone with a Sun? SunOS 4.1 (billed as Sun's transition >to SVR4) Yes, that's one thing that it is. It's also Sun's release that adds an asynchronous I/O mechanism, but the mechanism doesn't come from S5R4, as far as I know....
