bson_iter_codewscope(3) on Linux
The text 9d0302feae8f, as Debian 9 (Stretch) shipped it.
The bson_iter_codewscope() function acts similar to bson_iter_code() except for BSON_TYPE_CODEWSCOPE elements. It also will provide a pointer to the buffer for scope, which can be loaded into a bson_t using bson_init_static().
