Dear all: In dvb-app, like en50221_app_mmi.c, we will call en50221_app_mmi_create to create mmi struct. my question is why we use below assignments mmi->funcs = funcs; mmi->closecallback = NULL; mmi->displaycontrolcallback = NULL; mmi->keypadcontrolcallback = NULL; mmi->subtitlesegmentcallback = NULL; mmi->sceneendmarkcallback = NULL; mmi->scenecontrolcallback = NULL; mmi->subtitledownloadcallback = NULL; mmi->flushdownloadcallback = NULL; mmi->enqcallback = NULL; mmi->menucallback = NULL; mmi->listcallback = NULL; mmi->sessions = NULL; instead of using memset(mmi, NULL, sizeof(struct en50221_app_mmi); thanks for your help, miloody -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
