Thanks for the reply. Now it is clearer, to invoke brlapi, it is just
enough to have only instance of brltty running ( for one braille-display).
My reference to API is C-APIs. My objective is to Invoke C-APIs from an
existing application to interact with refreshable braille display and
LibLouise/daisy xml-integration. I think I have to go through a bit more
of the documentation before seeking further help/clarifications. Thank
you very much,Siju Samuel
