Member Data Documentation

MMAL_QUEUE_T* MMAL_COMPONENT_MODULE_T::callback_queue

Used to queue the callbacks we need to make to the client

MMAL_GRAPH_EVENT_CB MMAL_COMPONENT_MODULE_T::event_cb

callback for sending control port events to the client

void* MMAL_COMPONENT_MODULE_T::event_cb_data

callback data supplied by the client

MMAL_VC_CLIENT_BUFFER_CONTEXT_T MMAL_COMPONENT_MODULE_T::event_ctx

Used as the ctx for event buffers

MMAL_GRAPH_T MMAL_COMPONENT_MODULE_T::graph

Must be the first member!
