[net.unix-wizards] async disk I/O on Sys V*

boylan@dicomed.UUCP (Chris Boylan) (03/24/85)

I am thinking about imbedding System V in a product but
need a method of doing overlapped I/O (async).  Is there
such a facility in SV?  We currently have a SIII license
only and there doesnt appear to be anything in the SIII
manuals...

Alternatively, what kind of disk throughput can you get
out of SV?  I need about 75-125K/second (two sequential processes)
an st506 drive on a 68K or pdp-11/[24,73,84].  Can anyone quote
real numbers?

Knowledge based comments greatly appreciated,
