9 const bson_t *replacement,
10 const bson_t *opts,
11 bson_t *reply,
12 bson_error_t *error);
13
15 • collection: A mongoc_collection_t.
16
17 • selector: A bson_t containing the query to match the document for up‐
18 dating.
19
20 • replacement: A bson_t containing the replacement document.
21
22 • reply: Optional. An uninitialized bson_t populated with the update
23 result, or NULL.
24
25 • error: An optional location for a bson_error_t or NULL.
26
27 opts may be NULL or a BSON document with additional command options:
28
29 • writeConcern: Construct a mongoc_write_concern_t and use
30 mongoc_write_concern_append() to add the write concern to opts. See
31 the example code for mongoc_client_write_command_with_opts().
32
33 • sessionId: First, construct a mongoc_client_session_t with
34 mongoc_client_start_session(). You can begin a transaction with
35 mongoc_client_session_start_transaction(), optionally with a
36 mongoc_transaction_opt_t that overrides the options inherited from
37 collection, and use mongoc_client_session_append() to add the session
38 to opts. See the example code for mongoc_client_session_t.
39
40 • validate: Construct a bitwise-or of all desired
41 bson_validate_flags_t. Set to false to skip client-side validation of
42 the provided BSON documents.
43
44 • comment: A bson_value_t specifying the comment to attach to this com‐
45 mand. The comment will appear in log messages, profiler output, and
46 currentOp output. Requires MongoDB 4.4 or later.
47
48 • bypassDocumentValidation: Set to true to skip server-side schema val‐
49 idation of the provided BSON documents.
50
51 • collation: Configure textual comparisons. See Setting Collation Or‐
52 der, and the MongoDB Manual entry on Collation. Collation requires
53 MongoDB 3.2 or later, otherwise an error is returned.
54
55 • hint: A document or string that specifies the index to use to support
56 the query predicate.
57
58 • upsert: When true, creates a new document if no document matches the
59 query.
60
61 • let: A BSON document consisting of any number of parameter names,
62 each followed by definitions of constants in the MQL Aggregate Ex‐
63 pression language.
64
66 This function shall replace documents in collection that match selector
67 with replacement.
68
69 If provided, reply will be initialized and populated with the fields
70 matchedCount, modifiedCount, upsertedCount, and optionally upsertedId
71 if applicable. If there is a server error then reply contains either a
72 writeErrors array with one subdocument or a writeConcernErrors array.
73 The reply must be freed with bson_destroy().
74
76 Errors are propagated via the error parameter.
77
79 Returns true if successful. Returns false and sets error if there are
80 invalid arguments or a server or network error.
81
82 A write concern timeout or write concern error is considered a failure.
