## SYNOPSIS

-

  ```
  #include <infiniband/mlx5dv.h>
  int mlx5dv_dump_dr_domain(FILE *fout, struct mlx5dv_dr_domain *domain);
  int mlx5dv_dump_dr_table(FILE *fout, struct mlx5dv_dr_table *table);
  int mlx5dv_dump_dr_matcher(FILE *fout, struct mlx5dv_dr_matcher *matcher);
  int mlx5dv_dump_dr_rule(FILE *fout, struct mlx5dv_dr_rule *rule);
  ```

## DESCRIPTION

The Dump API (mlx5dv\_dump\_\*) allows the dumping of the existing rdma-core resources to the provided file. The output file format is vendor specific.

*mlx5dv\_dump\_dr\_domain()* dumps a DR Domain object properties to a specified file.

*mlx5dv\_dump\_dr\_table()* dumps a DR Table object properties to a specified file.

*mlx5dv\_dump\_dr\_matcher()* dumps a DR Matcher object properties to a specified file.

*mlx5dv\_dump\_dr\_rule()* dumps a DR Rule object properties to a specified file.

## RETURN VALUE

The API calls returns 0 on success, or the value of errno on failure (which indicates the failure reason). The calls are blocking - function returns only when all related resources info is written to the file.
