The SmartcardRawReply function transfers the data received from the card to the user buffer.
NTSTATUS
SmartcardRawReply(
PSMARTCARD_EXTENSION SmartcardExtension
);
SmartcardRawReply returns an NTSTATUS value. Possible values are the following.
Value | Meaning |
---|---|
STATUS_SUCCESS | Transmission successful. |
STATUS_BUFFER_TOO_SMALL | The user buffer is too small to hold the data. |
The driver must store the data coming from the reader into SmartcardExtension->SmartcardReply.Buffer and store the number of bytes returned from the card into SmartcardExtension->SmartcardReply.BufferLength. SmartcardRawReply then checks the validity of the data and copies the buffer back to the user buffer, including the protocol header.
SmartcardRawReply functions the same for WDM and VxD drivers.
