mongoc_database_find_collections()#
Warning
Deprecated since version 1.9.0: Use mongoc_database_find_collections_with_opts() instead.
Synopsis#
mongoc_cursor_t *
mongoc_database_find_collections (mongoc_database_t *database,
const bson_t *filter,
bson_error_t *error);
Description#
Fetches a cursor containing documents, each corresponding to a collection on this database.
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.
Parameters#
database
: A mongoc_database_t.filter
: A matcher used by the server to filter the returned collections. May beNULL
.error
: An optional location for a bson_error_t orNULL
.
Errors#
Errors are propagated via the error
parameter.
Returns#
This function returns a newly allocated mongoc_cursor_t that should be freed with mongoc_cursor_destroy() when no longer in use, or NULL in case of error. The user must call mongoc_cursor_next() on the returned mongoc_cursor_t to execute the initial command.
In the returned cursor each result corresponds to the server’s representation of a collection in this database.
The cursor functions mongoc_cursor_set_limit(), mongoc_cursor_set_batch_size(), and mongoc_cursor_set_max_await_time_ms() have no use on the returned cursor.
