Re: Can shared memory data be used as a signal like gtk-input-add does with a pipe?

[Marco Quezada <mquezada nlxcorp com>]

I'm not sure if this is the best and or only way to do it but I just have a
timeout that runs at a certain rate (10 Hz in my case) and looks at the value
of the variable in memory, if the value changes then it goes in and does
whatever processing it needs to do.

Hope this helps.
