Getting and Setting Pitch Yaw Roll from/to OpenGL modelview matrix

Question

I'm fairly sure the set code should look like this:

function setPYR(float pitch, float yaw, float roll) {
    glLoadIdentity();
    glRotatef(pitch, 1, 0, 0);
    glRotatef(yaw, 0, 1, 0);
    glRotatef(roll, 0, 0, 1);
}

How can I get the pitch, yaw and roll from the current modelview matrix?
