SYNOPSIS

9          bool
10          mongoc_collection_update_many (mongoc_collection_t *collection,
11                                         const bson_t *selector,
12                                         const bson_t *update,
13                                         const bson_t *opts,
14                                         bson_t *reply,
15                                         bson_error_t *error);
16

PARAMETERS

18       · collection: A mongoc_collection_t.
19
20       · selector: A bson_t containing the query to match documents for updat‐
21         ing.
22
23       · update: A bson_t containing the update to perform. If updating with a
24         pipeline, a bson_t array.
25
26       · reply:  Optional.  An  uninitialized bson_t populated with the update
27         result, or NULL.
28
29       · error: An optional location for a bson_error_t or NULL.
30
31       opts may be NULL or a BSON document with additional command options:
32
33       · writeConcern:  Construct  a  mongoc_write_concern_t  and   use   mon‐
34         goc_write_concern_append  to  add  the write concern to opts. See the
35         example code for mongoc_client_write_command_with_opts.
36
37       · sessionId:  First,  construct  a  mongoc_client_session_t  with  mon‐
38         goc_client_start_session.  You  can  begin  a  transaction  with mon‐
39         goc_client_session_start_transaction, optionally with a mongoc_trans‐
40         action_opt_t  that  overrides  the options inherited from collection,
41         and use mongoc_client_session_append to add the session to opts.  See
42         the example code for mongoc_client_session_t.
43
44       · validate:     Construct     a     bitwise-or     of    all    desired
45         bson_validate_flags_t. Set to false to skip client-side validation of
46         the provided BSON documents.
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
52         Order,  and the MongoDB Manual entry on Collation. Collation requires
53         MongoDB 3.2 or later, otherwise an error is returned.
54
55       · upsert: When true, creates a new document if no document matches  the
56         query.
57
58       · arrayFilters:  An array of filters specifying to which array elements
59         an update should apply.
60

DESCRIPTION

62       This function updates all documents in collection that match selector.
63
64       To update at most one document see mongoc_collection_update_one.
65
66       If you pass a non-NULL reply, it is filled out  with  fields   matched‐
67       Count, modifiedCount, and optionally upsertedId if applicable. If there
68       is a server error then reply contains either a "writeErrors" array with
69       one  subdocument  or  a  "writeConcernErrors"  array. The reply must be
70       freed with bson_destroy().
71

74       options.

ERRORS

79       Errors are propagated via the error parameter.
80

RETURNS

82       Returns  true  if successful. Returns false and sets error if there are
83       invalid arguments or a server or network error.
84
85       A write concern timeout or write concern error is considered a failure.
