OC_CreateIO

Configuration

OC_CreateIOConfiguration creates a scanner configuration from an

application-specific installation of rack sizes and installed modules.

See chapter 5 for more information.

Syntax:

int OC_CreateIOConfiguration(OCIOCFG *iocfg);

Parameters:

Description:

Modules can be specified by name or by mix and type. The function

automatically fills in the rest of the required information in the

OCIOCFG structure.

This function returns in

iocfg the scanner configuration information

obtained from the rack sizes and installed module types specified in

iocfg. The scanner configuration can then be downloaded to the

scanner with OC_DownloadIOConfiguration, which allows the

application to control the number of racks and their sizes and the

position and type of modules installed in the racks.

The OCIOCFG structure is defined as:

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 */

OCSLOTCFG SlotCfg[OCMAXSLOT];/* configuration for each

slot */

} OCIOCFG;

Return Value:

Considerations:

Supported in the DOS API library and the Windows NT API library

Parameter: Description:

iocfg Specifies the rack sizes and installed modules

Name: Value: Description:

SUCCESS 0 I/O configuration was read successfully

ERR_OCUNKNOWN 18 at least one module was not found in the internal database
