registered (even if the PRE NMI event has already happened.
Example
#define MESG_NUM 1
NUScClient client;
OSMesgQueue mesgQ;
OSMesg mesgBuf[MESG_NUM];
/* initialization of the message queue */
osCreateMesgQueue(&mesgQ, mesgBuf,MESG_NUM);
/* specify the retrace event and register clients to the Scheduler*/
nuScAddClient(&client, &mesgQ , NU_SC_RETRACE_MSG);
/* waiting for the retrace event */
osRecvMesg(&mesgQ, NULL, OS_MESG_BLOCK );
/* delete the registered clients*/
nuScRemoveClient(&client );
