OCIOCFG
Used by
OC_CreateIOConfiguration,
OC_GetIOConfiguration, and
OC_DownloadIOConfiguratio
n. Configuration information
for a system. 1, 2, or 3 racks
may be configured for up to
30 I/O modules. (Slot 0 is
reserved for the 1746 I/O PCI
Interface.) typedef struct tagOCIOCFG
{
BYTE
Rack1Size;/* number of slots in Rack 1 */
BYTE Rack2Size;/* number of slots in Rack 2 */
BYTE Rack3Size;/* number of slots in Rack 3 */
OCSLOTCFGSlotCfg[OCMAXSLOT];/* configuration for each slot */
} OCIOCFG;
OCSLOTCFG
Configuration information for
a module. The mix and type
codes together form a unique
identification for each
module. typedef struct tagOCSLOTCFG
{
BYTE
mix; /* mix code */
BYTE type; /* type code */
BYTE InputSize; /* number of inputs in bytes */
BYTE OutputSize; /* number of outputs in bytes */
WORD M0Size; /* size of M0 file in words */
WORD M1Size; /* size of M1 file in words */
WORD GSize; /* size of G file in words */
WORD *GData; /* pointer to array of length GSize words */
char *Name; /* pointer to module name string */
} OCSLOTCFG;
OCVERSIONINFO
Returned by
OC_GetVersionInfo. Software
and hardware version
numbers. typedef struct tagOCVERSIONINFO
{
WORD
APISeries; /* API series */
WORD APIRevision; /* API revision */
WORD ScannerFirmwareSeries;/* Scanner firmware series */
WORD ScannerFirmwareRevision;/* Scanner firmware revision */
WORD OCHardwareSeries;/* Hardware series */
WORD OCHardwareRevision;/* Hardware revision */
WORD OCdriverSeries /* OCdriver series - Windows NT only */
WORD OCdriverRevision /* Ocdriver reviwion - Windows NT only */
} OCVERSIONINFO;
STSFILE
