Function SCIPwriteCliqueGraph 

pub unsafe extern "C" fn SCIPwriteCliqueGraph(
    scip: *mut SCIP,
    fname: *const c_char,
    writenodeweights: c_uint,
) -> SCIP_RETCODE

writes the clique graph to a gml file

@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_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 - \ref SCIP_STAGE_SOLVED - \ref SCIP_STAGE_EXITSOLVE

@note there can be duplicated arcs in the output file

If @p writenodeweights is true, only nodes corresponding to variables that have a fractional value and only edges between such nodes are written.
