grep pbx_exec apps/*.c 
:) 

For example, apps/app_queue.c calls MixMonitor in about that way 
(lots of code skipped for clarity): 

    struct ast_app *mixmonapp = NULL;

    mixmonapp = pbx_findapp("MixMonitor");

    if (mixmonapp) { 
         ret = pbx_exec(qe->chan, mixmonapp, mixmonargs);
    } else 
         ast_log(LOG_WARNING, "Asked to run MixMonitor on this call, but cannot find the MixMonitor app!\n");
