Rotate player's head to face a point

Ok, I'm currently using Eric Hartman's Hook Code (you can find it with a quick search for grapple hook) but instead of creating an animation for hooking, I want to rotate the player so that the player's head is pointing towards the hook position. How would I do this?
If it helps, here is the extract of code that applies the physics:

//EGH: grapling hook forces
VectorF t;
t = getPosition() - hookPos;
float dist;
if( hookLen != -1 )
{
//if beyond hook length, apply force proportional to distance
dist = ((t.x * t.x) + (t.y * t.y) + (t.z * t.z));
if(dist > (hookLen*hookLen) )
{
//Con::warnf("Beyond HookLen");
mVelocity += (1000 * moveVec/ mMass) * TickSec;
//do something!
t.normalize();
F32 vMag;
vMag = mSqrt((mVelocity.x * mVelocity.x) + (mVelocity.y * mVelocity.y) + (mVelocity.z * mVelocity.z));
if(vMag != 0)
{
if(mAcos(mDot(t, mVelocity)/vMag) < 1.57)
{
mVelocity -= (mDot(t, mVelocity)/mDot(t, t)) * t ;
mVelocity.normalize();
mVelocity *= vMag;
}
}
}
else
{
//Con::warnf("Inside HookLen");
}
}
