That is my understanding (unless I am missing something here):

void handle_hotplug_event(struct event *re)
{
        struct rtas_event_hdr *rtas_hdr = re->rtas_hdr;
        struct rtas_hotplug_scn *hotplug;
        pid_t child;
        int status;
        char drc_index[11];
        char count[4];
        char *drmgr_args[] = { DRMGR_PROGRAM_NOPATH, "-c", NULL, NULL, 
NULL,
                        NULL, NULL, "-d4", "-V", NULL};
