Source 
pub unsafe extern "C" fn SCIPbranchLP(
    scip: *mut SCIP,
    result: *mut SCIP_RESULT,
) -> SCIP_RETCODE
Expand description

calls branching rules to branch on an LP solution; if no fractional variables exist, the result is SCIP_DIDNOTRUN; if the branch priority of an unfixed variable is larger than the maximal branch priority of the fractional variables, pseudo solution branching is applied on the unfixed variables with maximal branch priority

@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_SOLVING

See \ref SCIP_Stage “SCIP_STAGE” for a complete list of all possible solving stages.
