       msg_size        ACNET message size (in octets)
	num_edits	returns number of edit reports in "edit_list"
	edit_list	returns pointer to an array of edit reports
			(structures of type dbnews_t)
	[user_id]	returned console user ID
			(default is NULL)
	[display_name]	returned null terminated user display name
			(up to DBNEWS_DISPLAY_NAME_LEN characters)
			(default is NULL)
	[max_length]	maximum display name length to return
			(default is 0 which results in no length limit)
