mongoc_bulk_operation_execute — mongoc_bulk_operation_execute()
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. If ordered was specified to mongoc_collection_create_bulk_operation(), then forward progress will be stopped upon the first error.
It is only valid to call mongoc_bulk_operation_execute() once. The mongoc_bulk_operation_t must be destroyed afterwards.
reply is always initialized, even upon failure. Callers must call bson_destroy() to release this potential allocation.
bulk: A mongoc_bulk_operation_t.
reply: An uninitialized bson:bson_t.
error: An optional location for a bson_error_t or NULL.
Bulk Write Operations
Errors are propagated via the error parameter.
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 for examples.
See also mongoc_bulk_operation_get_hint, which gets the id of the server used even if the operation failed.
