Asynchronous I/O package or some hack for the System V 3.2

[Mark Thomas]

I need some code so that I can use some kind of Asynchonous witting and
reading to a disk file.  System V.4 has a package to do this.
HOwever, we need it for the 3.2 version. Has anybody written some code like
this? (Do I have to reinvent the wheel?)

If you do and can share som information with me please do.

What I have tough of is shared memory with other processes that really do
the reading and writing on a file. That wasy my main process will not block.

Thanks..
