Sorry, cut'n'paste error. I mean this part of your program (quoted literally):

                        printf("pvAssign Status:  %d\n",
                                pvAssign(vidOutputStat, pvName));
                        pvGet(vwrName[ii]);
/*                        strcpy(vidOutputStat, vwrName[ii]);*/
                        sprintf(vidOutputStat, "%s", vwrName[ii]);
                        printf("pvPut Status:     %d\n",
                                pvPut(vidOutputStat));

where you first

        pvAssign(vidOutputStat, pvName)

and then almost immediately afterwards (i.e. w/o waiting for the PV to be
connected)

        pvPut(vidOutputStat)

Cheers
