This chapter contains descriptions of the following callback prototypes:

>UICB_PromptConfirmation_t

>UICB_PromptForSmartCard_t

>UICB_PromptInt32_t

>UICB_PromptKeyComponent_t

>UICB_PromptPin_t

>UICB_PromptString_t

>UICB_PromptTokenPin_t

>UICB_ShowExportHeader_t

>UICB_ShowImportHeader_t

>UICB_ShowKeyComponent_t

>UICB_ShowSCBatchInfo_t

Example of Callback Prototype Use

The following code demonstrates callback prototype use using the PromptString callback.

/** Function prototype */

static CK_RV PromptString(

   const char *pszMessage,

   char *pBuf, CK_ULONG *pBufLen

);

/** Function implementation */

static CK_RV PromptString(

   const char* pszMessage, 

   char* pBuf,

   CK_ULONG* pBufLen

);

{

   CK_RV rv = CKR_OK;

   printf("%s", pszMessage);

   ReadLine(pBuf, *pBufLen);

   return rv;

}

int main(void){

   :

   :

   KM_Callbacks_t km_callbacks;

   memset(&km_callbacks, 0, sizeof(km_callbacks));

   km_callbacks.promptString       = PromptString;

   :

}
