# bson_append_code_with_scope()

## Synopsis

    bool
    bson_append_code_with_scope (bson_t *bson,
                                 const char *key,
                                 int key_length,
                                 const char *javascript,
                                 const bson_t *scope);

## Parameters

- `bson`: A bson_t.
- `key`: An ASCII C string containing the name of the field.
- `key_length`: The length of `key` in bytes, or -1 to determine the length with `strlen()`.
- `javascript`: A NULL-terminated UTF-8 encoded string containing the javascript fragment.
- `scope`: Optional bson_t containing the scope for `javascript`.

## Description

The bson_append_code_with_scope() function shall perform like bson_append_code() except it allows providing a scope to the javascript function in the form of a bson document.

If `scope` is NULL, this function appends an element with BSON type "code", otherwise with BSON type "code with scope".

## Returns

true if the operation was applied successfully, otherwise false and `bson` should be discarded.
