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”.


  • client: A mongoc_client_t.

  • db: The database name.

  • prefix: Optional prefix for gridfs collection names or NULL.

  • error: An optional location for a bson_error_t or NULL.


Errors are propagated via the error parameter.


On success, returns a mongoc_gridfs_t you must free with mongoc_gridfs_destroy(). Returns NULL upon failure and sets error.
