- * Update the fields of a vertex array structure.
+ * Update the fields of a vertex array object.
  * We need to do a few special things for arrays that live in
  * vertex buffer objects.
+ *
+ * \param array  the array to update
+ * \param dirtyBit  which bit to set in ctx->Array.NewState for this array
+ * \param elementSize  size of each array element, in bytes
+ * \param size  components per element (1, 2, 3 or 4)
+ * \param type  datatype of each component (GL_FLOAT, GL_INT, etc)
+ * \param stride  stride between elements, in elements
+ * \param normalized  are integer types converted to floats in [-1, 1]?
+ * \param ptr  the address (or offset inside VBO) of the array data
