is there an opengl function for drawing a circle?

Nope. Use a for-loop and some trigonometry and draw them yourself instead.

any code?

How about this:

void circle(float radius)
{
int x;
glBegin(GL_LINE_LOOP);
for (x=0;x<360;x+=5)
{
glVertex3f(cos(x*PI/180)radius,sin(xPI/180)*radius,0.0);
}
glEnd();
}
