Does O_SYNC work on your platform?

[Alan M. Fisch]

I am interested in the behavior of O_SYNC on specific UNIX platforms.

For years I have understood that O_SYNC has been broken in the System V
code AT&T licenses to its vendors, and few vendors have made any changes
to it.  Thus, using O_SYNC did not actually provide the synchronous
write expected. 

With most System V implementation up to Release 3, I believe the
problems to be fixed.  Any definitive information you have about specific
platforms (both Sys V and BSD) would be of great use in some research I 
am doing.

Please respond via Email and I will post a summary.  Thanks in advance 
for the information.
