mongoc_cursor_set_limit()¶
Synopsis¶
bool
mongoc_cursor_set_limit (mongoc_cursor_t *cursor, int64_t limit);
Parameters¶
cursor: A mongoc_cursor_t.limit: The maximum number of documents to retrieve for this query.
Description¶
Limits the number of documents in the result set.
This function is useful for setting the limit on a cursor after the cursor is created, but before any calls to mongoc_cursor_next(). It can also be used to pass a negative limit: The limit parameter to mongoc_cursor_set_limit is signed, although for backward-compatibility reasons the limit parameter to mongoc_collection_find() is not.
Calling this function after mongoc_cursor_next() has no effect.
Returns¶
Returns true on success. If any arguments are invalid, returns false and leaves the limit unchanged.
