Remarks

This function is not redirected, but calling the function when inside a Remote Desktop session will not result in an error. It only means that the result will be from the remote computer instead of the local computer.

This function sets the provider name, while SCardGetCardTypeProviderName can be used to retrieve the provider name.

Examples

The following example shows how to specify the card type provider name.

LPTSTR            szNewProvName = _T("My Provider Name");
LPTSTR            szCardName = _T("WindowsCard");
LONG              lReturn = SCARD_S_SUCCESS;

// Set the card type provider name.
// hContext was set by SCardEstablishContext.
lReturn = SCardSetCardTypeProviderName(hContext,
                                      szCardName,
                                      SCARD_PROVIDER_CSP,
                                      szNewProvName);
if ( SCARD_S_SUCCESS != lReturn )
{
    printf("Failed SCardSetCardTypeProviderName - %x\n", lReturn);
    exit(1);
}

Note

The winscard.h header defines SCardSetCardTypeProviderName as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
