mongoc_collection_drop_index_with_opts (mongoc_collection_t *collection,
                                        const char *index_name,
                                        const bson_t *opts,

  • collection: A mongoc_collection_t.
  • index_name: A string containing the name of the index.
  • error: An optional location for a bson_error_t or NULL.

opts may be NULL or a BSON document with additional command options:

  • writeConcern: Construct a mongoc_write_concern_t and use mongoc_write_concern_append() to add the write concern to opts. See the example code for mongoc_client_write_command_with_opts().
  • sessionId: First, construct a mongoc_client_session_t with mongoc_client_start_session(). You can begin a transaction with mongoc_client_session_start_transaction(), optionally with a mongoc_transaction_opt_t that overrides the options inherited from collection, and use mongoc_client_session_append() to add the session to opts. See the example code for mongoc_client_session_t.
  • collation: Configure textual comparisons. See Setting Collation Order, and the MongoDB Manual entry on Collation. Collation requires MongoDB 3.2 or later, otherwise an error is returned.
  • serverId: To target a specific server, include an int32 "serverId" field. Obtain the id by calling mongoc_client_select_server(), then mongoc_server_description_id() on its return value.

This function requests than an index on collection be dropped.

If no write concern is provided in opts, the collection's write concern is used.

Errors are propagated via the error parameter.

Returns true if successful. Returns false and sets error if there are invalid arguments or a server or network error.
