emit传递python函数

在Python中，emit是一种信号槽机制，用于传递信号并触发与之连接的函数。emit通过发出号，将参数传递给与之连接的函数。在上述的示例代码中，emit被用于触发连接到trigger信号的epics_autoprocess函数。当tcp_epics_thread线程中的trigger信号被发出时，参数msg将被传递给epics_autoprocess函数，并执行相应的操作。这种方式可以实现线程间的通信和函数的调用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
