mongoc_collection_drop_index_with_opts()#

Synopsis#

bool
mongoc_collection_drop_index_with_opts (mongoc_collection_t *collection,
                                        const char *index_name,
                                        const bson_t *opts,
                                        bson_error_t *error);

Parameters#

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.

Description#

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#

Errors are propagated via the error parameter.

Returns#

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