Function SCIPtransformVar 

pub unsafe extern "C" fn SCIPtransformVar(
    scip: *mut SCIP,
    var: *mut SCIP_VAR,
    transvar: *mut *mut SCIP_VAR,
) -> SCIP_RETCODE

gets and captures transformed variable of a given variable; if the variable is not yet transformed, a new transformed variable for this variable is created

@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_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
