How to describe a surface with an inner hole？

I found this:

How-To: Using SC::Store::Utils::TriangulateFace

TriangulateFace takes several arguments (cf. SC::Store::Utils::TriangulateFace) to triangulate a supplied polygonal face. While most arguments are straightforward, the face_list is a little more complicated. The first number in the face list array indicates the number of indices defining a face. This is followed by those indices (in the points array). This pattern repeats for subsequent faces. If you have two triangles, the face list array might be as follows; { 3, 0, 1, 2, 3, 2, 3, 0 } …

does that mean if I want to create a surface with hole, I should triangulate the face by calling
SC::Store::Utils::TriangulateFace first.
