单选题
The API changes should provide both source and binary( )for programs written to the original API.That is, existing program binaries should continue to operate when run on a system supporting the new API.In addition, existing()that are re-compiled and run on a system supporting the new API should continue to operate.Simply put, the AP(I ) for multicast receivers that specify source filters should not break existing programs.The changes to the API should be as small as possible in order to simplicity the task of converting existing(_______) receiver applications to use source filters. Applications should be able to delete when the new() filter APIs are unavailable(e.g., calls fail with the ENOTSUPP error) and react gracefully(e.g., revert to old non-source-filter API or display a meaningful error message to the user).

根据题目描述,API的变化应该为原始API编写的程序提供源代码和二进制代码的支持。这意味着在新的API支持的系统中运行现有的程序二进制文件应该继续运行。此外,重新编译并在新API支持的系统中运行的现有程序也应该继续运行。简单来说,指定源过滤器的多播接收者的API不应该破坏现有程序。API的更改应尽可能小,以便简化将现有接收应用程序转换为使用源过滤器的任务。当新的过滤器API不可用(例如,调用返回ENOTSUPP错误)时,应用程序应该能够删除并优雅地响应(例如,恢复到旧的非源过滤器API或向用户显示有意义的错误消息)。根据上下文,“multicast”(多播)是最符合题意的选项,因此答案是A。
