本文介绍了一种用于检测实时程序中非实时接口调用的方法，通过发送sigdebug信号来提醒开发者避免使用可能引起非实时行为的系统调用，如open、close、write等。配置项CONFIG_XENO_OPT_DEBUG_TRACE_RELAX可用于追踪非实时调用的具体位置。

本程序可以查看实时程序中是否调用了非实时接口，如果是的话会发送sigdebug信号提示或结束，开发者写实时程序的时候可以加上以防止写了非实时代码。测试发现调用open,close write等常用inux系统调用都会进入非实时模式。打开CONFIG_XENO_OPT_DEBUG_TRACE_RELAX可以跟踪非实时调用的位置。
