Subject: /dev/vcs - poll for changes?
Date: Fri, 17 Apr 2009 16:05:26 +0100	[thread overview]
Message-ID: <1239980726652@dmwebmail.dmwebmail.chezphil.org> (raw)

Dear Experts,

Is there a way to detect when the content of a /dev/vcs* has changed?  
I have some code that currently polls, which is obviously sub-optimal.  
I was hoping that there would be some trick like look at the 
modification time, but I haven't found anything.  If this isn't 
currently possible, how easily could it be added?  What would the 
preferred API be, if it were added?

Thanks for any suggestions.

Phil.
