SYNOPSIS
typedef struct _mongoc_index_model_t mongoc_index_model_t;
mongoc_index_model_t *
mongoc_index_model_new (const bson_t *keys, const bson_t *opts);
void mongoc_index_model_destroy (mongoc_index_model_t *model);
bool
mongoc_collection_create_indexes_with_opts (mongoc_collection_t *collection,
mongoc_index_model_t **models,
size_t n_models,
const bson_t *opts,
bson_t *reply,
bson_error_t *error);
PARAMETERS
• collection: A mongoc_collection_t <>.
• models: An array of mongoc_index_model_t *.
• n_models: The number of models.
• opts: Optional options.
• reply: A maybe-NULL pointer to overwritable storage <https://www.mongodb.com/docs/languages/c/c-driver/
current/libbson/guides/lifetimes/#overwritable-storage> for a bson_t <https://www.mongoc.org/libbson/
current/bson_t.html> to contain the results.
• 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 <https://www.mongodb.com/docs/
languages/c/c-driver/current/libmongoc/guides/bulk/#setting-collation-order>, and the MongoDB Manual
entry on Collation <https://www.mongodb.com/docs/manual/reference/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.
Additional options passed in opts are appended to the createIndexes command. See the MongoDB Manual for
createIndexes <https://www.mongodb.com/docs/manual/reference/command/createIndexes/> for all supported
options.
If no write concern is provided in opts, the collection's write concern is used.
mongoc_index_model_t
Each mongoc_index_model_t represents an index to create. mongoc_index_model_new includes:
• keys Expected to match the form of the key field in the createIndexes <https://www.mongodb.com/docs/
manual/reference/command/createIndexes/> command.
• opts Optional index options appended as a sibling to the key field in the createIndexes <https://www
.mongodb.com/docs/manual/reference/command/createIndexes/> command.
DESCRIPTION
This function wraps around the createIndexes <https://www.mongodb.com/docs/manual/reference/command/
createIndexes/> command.
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.
