* @addtogroup Interfaces
* @{
* The PPB_BrokerTrusted interface provides access to a trusted broker
* with greater privileges than the plugin. The interface only supports
* out-of-process plugins and is to be used by proxy implementations. All
* functions should be called from the main thread only.
* A PPB_BrokerTrusted resource represents a connection to the broker. Its
* lifetime controls the lifetime of the broker, regardless of whether the
* handle is closed. The handle should be closed before the resource is
* released.
struct PPB_BrokerTrusted {
* Returns a trusted broker resource.
PP_Resource (*CreateTrusted)(PP_Instance instance);
* Returns true if the resource is a trusted broker.
PP_Bool (*IsBrokerTrusted)(PP_Resource resource);
* Connects to the trusted broker. It may have already
* been launched by another instance.
* The plugin takes ownership of the handle once the callback has been called
* with a result of PP_OK. The plugin should immediately call GetHandle and
* begin managing it. If the result is not PP_OK, the browser still owns the
* handle.
* Returns PP_ERROR_WOULD_BLOCK on success, and invokes
* the |connect_callback| asynchronously to complete.
* As this function should always be invoked from the main thread,
* do not use the blocking variant of PP_CompletionCallback.
* Returns PP_ERROR_FAILED if called from an in-process plugin.
int32_t (*Connect)(PP_Resource broker,
struct PP_CompletionCallback connect_callback);
* Gets the handle to the pipe. Use once Connect has completed. Each instance
* of this interface has its own pipe.
* Returns PP_OK on success, and places the result into the given output
* parameter. The handle is only set when returning PP_OK. Calling this
* before connect has completed will return PP_ERROR_FAILED.
int32_t (*GetHandle)(PP_Resource broker, int32_t* handle);
