                               const bson_t *selector,
                               const bson_t *update,
                               const bson_t *opts,
                               bson_t *reply,
                               bson_error_t *error);

Parameters

opts may be NULL or a BSON document with additional command options:

Description

This function updates all documents in collection that match selector.

To update at most one document see mongoc_collection_update_one.

If you pass a non-NULL reply, it is filled out with fields  matchedCount, modifiedCount, and optionally upsertedId if applicable. If there is a server error then reply contains either a "writeErrors" array with one subdocument or a "writeConcernErrors" array. The reply must be freed with bson_destroy().

Errors are propagated via the error parameter.

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