Function SCIPwriteVarsLinearsumExact 

pub unsafe extern "C" fn SCIPwriteVarsLinearsumExact(
    scip: *mut SCIP,
    file: *mut FILE,
    vars: *mut *mut SCIP_VAR,
    vals: *mut *mut SCIP_RATIONAL,
    nvars: c_int,
    type_: c_uint,
) -> SCIP_RETCODE

print the given variables and rational coefficients as linear sum in the following form c1 <x1> + c2 <x2> … + cn <xn>

This string can be parsed by the method SCIPparseVarsLinearsum().

@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_INITSOLVE - \ref SCIP_STAGE_SOLVING - \ref SCIP_STAGE_SOLVED - \ref SCIP_STAGE_EXITSOLVE - \ref SCIP_STAGE_FREETRANS

@note The printing process is done via the message handler system.
