Example:

int retcode, numslots, i;
char module_name[] = ”1746-BAS”;
iocfg.Rack1Size = 10; /* 10 slot chassis */
iocfg.Rack2Size = 7; /* 7 slot chassis */
iocfg.Rack3Size = 0; /* Only 2 chassis */
numslots = iocfg.Rack1Size + iocfg.Rack2Size + iocfg.Rack3Size;
for ( i=1; i<numslots; i++ ){
iocfg.SlotCfg[i].mix = OCEMPTYMIX;
iocfg.SlotCfg[i].type = OCEMPTYTYPE; /* Empty all slots */
}
iocfg.SlotCfg[6].mix = 35;
iocfg.SlotCfg[6].type = 6;
/* Slot 6 has 1746-BAS module */
or
iocfg.SlotCfg[6].name = module_name; /* Use name instead */
.
.
/* Add additional module information to */
. /* match the physical I/O configuration */
