XMMatrixMultiply vs using the * operator

Question

What's the difference between multiplying Matrices together versus using the XMMatrixMultiply?

XMMATRIX aXb;       aXb =       XMMatrixMultiply( a, b );
XMMATRIX aXb_Xc;    aXb_Xc =    XMMatrixMultiply( aXb, c );

versus

XMMATRIX delta = a * b * c;

Answer 1

I don't think there is a difference. XMMatrixMultiply is there for people using C instead of C++.
