Can't find how this is done. Seems everyone using added buffer through the C-script function add_buffer() already knows how to free the buffer once it is not going to be used again. Is this done automatically when the application is closed? Maybe some kind soul can fill me in on this mystery Pretty Please! The function free(buffer) shown in the manual does not seem to be that functional in A660 which I am using.

thanks, tindust

OK, found it now after posting a question of course. In different version manual under add_buffer:
buffer - pointer to the buffer with the file content, or NULL for removing the buffer from the file system

thanks anyway
