mongoc_collection_create_index_with_opts()¶
Synopsis¶
bool
mongoc_collection_create_index_with_opts (mongoc_collection_t *collection,
const bson_t *keys,
const mongoc_index_opt_t *index_opts,
const bson_t *command_opts,
bson_t *reply,
bson_error_t *error);
Deprecated¶
This function is deprecated and should not be used in new code. See Creating Indexes.
Parameters¶
collection
: A mongoc_collection_t.keys
: Abson_t
.index_opts
: A mongoc_index_opt_t.reply
: An optional location for abson_t
which will store the server’s reply.error
: An optional location for a bson_error_t orNULL
.
command_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 toopts
. 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 fromcollection
, and use mongoc_client_session_append() to add the session toopts
. See the example code for mongoc_client_session_t.
Description¶
This function will request the creation of a new index.
This function will use the createIndexes
command.
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.
