UCHAR | PHGetDefaultProtocol (PUCHAR, DWORD) |
Get the default protocol used immediately after reset. | |
UCHAR | PHGetAvailableProtocols (PUCHAR, DWORD) |
Get the protocols supported by the card. | |

Definition in file prothandler.h.
Get the protocols supported by the card.
These protocols are returned from the function as bit masks.

DWORD PHSetProtocol | ( | struct ReaderContext * | rContext, | |
DWORD | dwPreferred, | |||
UCHAR | ucAvailable, | |||
UCHAR | ucDefault | |||
) |
Determine which protocol to use.
SCardConnect has a DWORD dwPreferredProtocols that is a bitmask of what protocols to use. Basically, if T=N where N is not zero will be used first if it is available in ucAvailable. Otherwise it will always default to T=0.
IFDSetPTS() is _always_ called so that the driver can initialise its data
