# mongoc_client_get_gridfs()

## Synopsis

    mongoc_gridfs_t *
    mongoc_client_get_gridfs (mongoc_client_t *client,
                              const char *db,
                              const char *prefix,
                              bson_error_t *error);

The `mongoc_client_get_gridfs()` function shall create a new mongoc_gridfs_t. The `db` parameter is the name of the database which the gridfs instance should exist in. The `prefix` parameter corresponds to the gridfs collection namespacing; its default is “fs”, thus the default GridFS collection names are “fs.files” and “fs.chunks”.

- `db`: The database name.
- `prefix`: Optional prefix for gridfs collection names or `NULL`.
- `error`: An optional location for a bson_error_t or `NULL`.

## Returns
