NAME

6       mongoc_database_get_collection_names_with_opts      -      mongoc_data‐
7       base_get_collection_names_with_opts()
8

SYNOPSIS

10          char **
11          mongoc_database_get_collection_names_with_opts (mongoc_database_t *database,
12                                                          const bson_t *opts,
13                                                          bson_error_t *error);
14
15       Fetches a NULL terminated array of NULL-byte terminated  char*  strings
16       containing the names of all of the collections in database.
17
18       This  function  is considered a retryable read operation.  Upon a tran‐
19       sient error (a network error, errors due to replica set failover, etc.)
20       the  operation  is  safely retried once.  If retryreads is false in the
21       URI (see mongoc_uri_t) the retry behavior does not apply.
22

PARAMETERS

24       · database: A mongoc_database_t.
25
26       · opts: A bson_t containing additional options.
27
28       · error: An optional location for a bson_error_t or NULL.
29
30       opts may be NULL or a BSON document with additional command options:
31
32       · sessionId:  First,  construct  a  mongoc_client_session_t  with  mon‐
33         goc_client_start_session.  You  can  begin  a  transaction  with mon‐
34         goc_client_session_start_transaction, optionally with a mongoc_trans‐
35         action_opt_t  that overrides the options inherited from database, and
36         use mongoc_client_session_append to add the session to opts. See  the
37         example code for mongoc_client_session_t.
38
39       · serverId:  To  target  a specific server, include an int32 "serverId"
40         field. Obtain the id  by  calling  mongoc_client_select_server,  then
41         mongoc_server_description_id on its return value.
42
43       For a list of all options, see the MongoDB Manual entry on the listCol‐
44       lections command.
45

ERRORS

47       Errors are propagated via the error parameter.
48

RETURNS

50       A NULL terminated array of NULL terminated char* strings that should be
51       freed with bson_strfreev(). Upon failure, NULL is returned and error is
52       set.
53

EXAMPLES

55          {
56             bson_t opts = BSON_INITIALIZER;
57             mongoc_read_concern_t *rc;
58             bson_error_t error;
59             char **strv;
60             unsigned i;
61
62             rc = mongoc_read_concern_new ();
63             mongoc_read_concern_set_level (rc, MONGOC_READ_CONCERN_LEVEL_MAJORITY);
64             mongoc_read_concern_append (rc, &opts);
65             if ((strv = mongoc_database_get_collection_names_with_opts (
66                    database, &opts, &error))) {
67
68                for (i = 0; strv[i]; i++)
69                   printf ("%s\n", strv[i]);
70
71                bson_strfreev (strv);
72             } else {
73                fprintf (stderr, "Command failed: %s\n", error.message);
74             }
75
76             mongoc_read_concern_destroy (rc);
77             bson_destroy (&opts);
78          }
