Function SCIPisLPSolBasic 

pub unsafe extern "C" fn SCIPisLPSolBasic(scip: *mut SCIP) -> c_uint

returns whether the current LP solution is basic, i.e. is defined by a valid simplex basis

@return whether the current LP solution is basic, i.e. is defined by a valid simplex basis.

@pre This method can be called if @p scip is in one of the following stages: - \ref SCIP_STAGE_SOLVING
