Function Documentation

◆ PHSetProtocol()

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
