MONGOC_DATABAS...AMES_WITH_OPTS(3)

💖 mongoc_database_get_collection_names_with_opts(3) 💖

okay bestie, welcome to the libmongoc manual. The header is out here looking like MONGOC_DATABAS...AMES_WITH_OPTS(3) because terminal truncation is doing the absolute most 😭, but the full function is mongoc_database_get_collection_names_with_opts, and yes she is iconic.

🌸 SYNOPSIS 🌸

char **
mongoc_database_get_collection_names_with_opts (mongoc_database_t *database,
                                                const bson_t *opts,
                                                bson_error_t *error);

Fetches a NULL terminated array of NULL-byte terminated char* strings containing the names of all of the collections in database. slay.

This function is considered a retryable read operation. Upon a transient error (a network error, errors due to replica set failover, etc.) the operation is safely retried once. If retryreads is false in the URI (see mongoc_uri_t) the retry behavior does not apply. periodt.

🎀 PARAMETERS 🎀

• database — A mongoc_database_t. the main character.
• opts — A bson_t containing additional options.
• error — An optional location for a bson_error_t or NULL.

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

• sessionId — First, construct a mongoc_client_session_t with mongoc_client_start_session(). You can begin a transaction with mongoc_client_session_start_transaction(), optionally with a mongoc_transaction_opt_t that overrides the options inherited from database, and use mongoc_client_session_append() to add the session to opts. See the example code for mongoc_client_session_t.
• serverId — To target a specific server, include an int32 "serverId" field. Obtain the id by calling mongoc_client_select_server(), then mongoc_server_description_id() on its return value.

For a list of all options, see the MongoDB Manual entry on the listCollections command. iykyk 💅

💀 ERRORS 💀

Errors are propagated via the error parameter. that’s the tea 🍵

---

✨ RETURNS ✨

A NULL terminated array of NULL terminated char* strings that should be freed with bson_strfreev(). Upon failure, NULL is returned and error is set. no cap.

🦋 EXAMPLES 🦋

this example is giving read-concern majority realness, bestie:

{
   bson_t opts = BSON_INITIALIZER;
   mongoc_read_concern_t *rc;
   bson_error_t error;
   char **strv;
   unsigned i;

   rc = mongoc_read_concern_new ();
   mongoc_read_concern_set_level (rc, MONGOC_READ_CONCERN_LEVEL_MAJORITY);
   mongoc_read_concern_append (rc, &opts);
   if ((strv = mongoc_database_get_collection_names_with_opts (
          database, &opts, &error))) {

      for (i = 0; strv[i]; i++)
         printf ("%s\n", strv[i]);

      bson_strfreev (strv);
   } else {
      fprintf (stderr, "Command failed: %s\n", error.message);
   }

   mongoc_read_concern_destroy (rc);
   bson_destroy (&opts);
}
