void CMyliebiaoView::DrawWave(void)
{
//建立列表显示区
//**********************************
listName = glGenLists(1);
glNewList (listName, GL_COMPILE_AND_EXECUTE);//GL_COMPILE_AND_EXECUTEGL_COMPILE

//***********************************

//画正弦曲线
GLdouble x;
glPointSize(2.0);
glColor3f(0.0,0.0,0.0);
glBegin(GL_LINE_STRIP);

//for(x=0; x<=40; x+=0.01)
while(m_dCount<=40)

{

glVertex2d(m_dCount,C+50/**rand()*/*sin(0.025*Pi*m_dCount));
m_dCount += 1;

glVertex2d(m_dCount,C+50/**rand()*/*sin(0.025*Pi*m_dCount));

}
m_dCount = 0;

glEnd();
// glFlush();
GLuint i;
glPushMatrix();
for (i = 0; i <5; i++)
glCallList (listName);
//调用列表显示
glFlush ();
glPopMatrix();
}
像上面这一段程序如何用双缓存进行重绘，能给出程序吗？我是一个初学者，望高手指教，谢谢!
