MONGOC_BULK_OPERATION_EXECUTE(3) libmongoc MONGOC_BULK_OPERATION_EXECUTE(3)

SYNOPSIS

uint32_t
mongoc_bulk_operation_execute (mongoc_bulk_operation_t *bulk,

bson_t *reply,
bson_error_t *error);


This function executes all operations queued into the bulk operation. Unless ordered: false was specified in the opts passed to mongoc_collection_create_bulk_operation_with_opts() <>, then forward progress will be stopped upon the first error.

It is only valid to call mongoc_bulk_operation_execute() <> once on the same mongoc_bulk_operation_t <>. Calling repeatedly results in error. Call mongoc_bulk_operation_destroy() <> to destroy bulk afterwards.

Changed in version 2.0.0: Calling mongoc_bulk_operation_execute() <> repeatedly results in an error.

Warning:

reply is always initialized, even upon failure. Callers must call bson_destroy() <https://www.mongoc.org/libbson/current/bson_destroy.html> to release this potential allocation.


PARAMETERS


ERRORS

Errors are propagated via the error parameter.

RETURNS

On success, returns the server id used. On failure, returns 0 and sets error.

A write concern timeout or write concern error is considered a failure.

The reply document counts operations and collects error information. See Bulk Write Operations <https://www.mongodb.com/docs/languages/c/c-driver/current/libmongoc/guides/bulk/> for examples.
