I had been trying and searching but end up failing to create a variable using lua extension, and access the variable from the vlc source file (avi.c). I am trying to pass some value from lua extension to be used by some function in avi.c

Any how I can achieve this or is there other better way? Example will be much appreciated as I am really confused by vlc programming..

Is there any developer tutorial regarding variables and passing the values? (Most importantly between a lua extension and the avi.c)
Need help here thanks.
