Example:

OCIOCFG iocfg;

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 */

iocfg.SlotCfg[6].name = module_name; /* Use name instead */

. /* Add additional module information to */

. /* match the physical I/O configuration */

retcode = OC_CreateIOConfiguration( &iocfg );

/* Use OC_DownloadIOConfiguration() to download the information */
