function<void()> cb = bind(&Printer::print, printer); usingCallback(cb); 此处需注意,在绑定成员函数时,参数还需要一个类指针,因为成员函数参数默认均有一个this指针。
std::function<void()>mCallBack; QTimer timer; };intmain(intargc,char*argv[]){ QApplication a(argc, argv); auto cb { [](){ std::cout<<"timer out..."<<std::endl; } }; Handle h(cb);returna.exec(); } 首先得到了拉姆达函数,然后通过构造函数传递给Handle对象,传递时执行了拉姆达到...

function void print_state(); $display("@%0t: time = %s", $time); endfunction 3、function中可以使用return得到函数的返回值,不使用return时,与函数名字相同的变量的值就是返回值。 function bit tranmit(); //其他语句 return ~ifc.cb.error; endfunction 4、从函数返回一个数组有两种方法:第一中方...
