#### Declaration [src]

    gboolean
    clapper_enhancer_proxy_extra_data_lists_value (
      ClapperEnhancerProxy* proxy,
      const gchar* key,
      const gchar* value
    )

#### Description [src]

A convenience function to check whether `proxy` plugin file has an extra data field with `key` that among separated list of values includes `value` (works on single value lists too).

For example, when extra data in the plugin is `X-Schemes=https;http`, calling this function with “X-Schemes” as key and “http” as value will return `TRUE`.

It is also safe to call this function when there is no such `key` in plugin info file. Use `clapper_enhancer_proxy_get_extra_data()` if you need to know whether key exists.
