[Scip] getting statistics on LP relaxation

[Luigi De Giovanni]

Dear all,

I have a branch-and-price algorithm and I am going to run some 
computational experiments. I would like to collect some statistics on 
the LP relaxation at the root node.
I use

scip->stat->rootlowerbound

to get the value of the linear relaxation at the root node. Is this correct?

How can I get the overall time needed to solve the LP relaxation at the 
root node?

Thank you very much!
