Function SCIPinterruptSolve 

pub unsafe extern "C" fn SCIPinterruptSolve(
    scip: *mut SCIP,
) -> SCIP_RETCODE

informs \SCIP that the solving process should be interrupted as soon as possible (e.g., after the current node has been solved)

@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 @p 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_SOLVING - \ref SCIP_STAGE_SOLVED - \ref SCIP_STAGE_EXITSOLVE - \ref SCIP_STAGE_FREETRANS

@note the \SCIP stage does not get changed
