Function SCIPcreateSolCopy 

pub unsafe extern "C" fn SCIPcreateSolCopy(
    scip: *mut SCIP,
    sol: *mut *mut SCIP_SOL,
    sourcesol: *mut SCIP_SOL,
) -> SCIP_RETCODE

creates a copy of a primal solution; note that a copy of a linked solution is also linked and needs to be unlinked if it should stay unaffected from changes in the LP or pseudo solution

@return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref SCIP_Retcode “SCIP_RETCODE” for a complete list of error codes.

@pre This method can be called if SCIP is in one of the following stages: - \ref SCIP_STAGE_PROBLEM - \ref SCIP_STAGE_TRANSFORMING - \ref SCIP_STAGE_TRANSFORMED - \ref SCIP_STAGE_INITPRESOLVE - \ref SCIP_STAGE_PRESOLVING - \ref SCIP_STAGE_EXITPRESOLVE - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_INITSOLVE - \ref SCIP_STAGE_SOLVING
