I want to implement a branch and bound algorithm. How to warm start dual simplex in Cylp?

Hello, I'm trying to implement my own simple branch and bound algorithm using Cylp. I want to use the basis in the parent node to warm start the child node. In the CyClpSimplex, I didn't find any API to do this. In this page, https://www.coin-or.org/Doxygen/Clp/classCoinWarmStartPrimalDual.html, I find that Clp support warm start. Do you have some idea? Thanks a lot.
