Deprecated

This function is deprecated and should not be used in new code. See create-indexes.

Parameters

Description

This function will request the creation of a new index.

This function will use the createIndexes command if available on the MongoDB server. If not, it will fallback to inserting into system.indexes for compatibility with MongoDB <= 2.4.

The server’s reply is stored in reply.

If no write concern is provided in command_opts, the collection’s write concern is used.

See mongoc_index_opt_t for options on creating indexes.

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.

reply is always initialized and must be destroyed with bson_destroy(). If the server is running an obsolete version of MongoDB then reply may be empty, though it will still be initialized.
