[vlc-devel] How to share a variable between qt4 ui (c++) and playlist thread (c)

[Fayyaz Khan]

Thank you Remi.

I understand that well and probably that is not a problem in my case.

The shared variable (char array) that i wish to create will be updated 
by a dialog in the beginning of the program (though it can be chosen 
from a list of dynamic options), before playlist components picks it up. 
So there will be no sync issue.

Moreover, i am using PL Lock / unlock in both scenarios to ensure 
synchronized access.

Could you please elaborate a little more on a good location in source 
code to prevent other include file issues? Right now i am a victim of those.

Thank you
Fayyaz
