OCXcip_SetIdObject

Syntax

int OCXcip_SetIdObject (OCXHANDLE apihandle,

OCXCIPIDOBJ *idoObject);

Parameters

apihandle

handle returned by previous call to OCXcip_Open

idobject

Pointer to structure of type OCXCIPIDOBJ

Description

OCXcip_SetIdObject allows an application to customize the identity of a module.

apihandle must be a valid handle returned from OCXcip_Open.

idobject is a pointer to a structure of type OCXCIPIDOBJ. The members of this

structure will be updated with the module identity data.

The following example defines the OCXCIPIDOBJ structure:

typedef struct tagOCXCIPIDOBJ

{

WORD VendorID; //Vendor ID Number

WORD DeviceType; //General product type

WORD ProductCode: //Vendor-specific product identifier

BYTE MajorRevision; //Major revision level

BYTE MinorRevision; //Minor revision level

DWORD SerialNo; //Module serial number

BYTE Name [32]; //Text module name (null-terminated)

} OCXCIPIDOBJ;

Return Value

OCX_SUCCESS

ID object was retrieved successfully

OCX_ERR_NOACCESS

apihandle does not have access

Example

OCXCIPHANDLE apihandle;

OCXCIPIDOBJ idobject;

OCXcip_GetIdObject(apihandle,&idobject); //Get default info

// Change module name

strcpy ((char*) idobject.Name, "Custom Module Name");

OCXcip_SetIdObject (apiHandle, &idobject);
