Function scip_sys::SCIPgetConsNVars

pub unsafe extern "C" fn SCIPgetConsNVars(
    scip: *mut SCIP,
    cons: *mut SCIP_CONS,
    nvars: *mut c_int,
    success: *mut c_uint
) -> SCIP_RETCODE

method to collect the number of variables of a constraint

@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 success pointer indicates if the contraint handler was able to return the number of variables

@note It might be that a constraint handler does not support this functionality, in that case the success pointer is set to FALSE
