The SmartcardT0Reply function transfers the data received from the card to the user buffer.
Syntax
NTSTATUS SmartcardT0Reply(
PSMARTCARD_EXTENSION SmartcardExtension
);
Parameters
- SmartcardExtension
[in] Points to the smart card extension of the device.
Return Value
SmartcardT0Reply returns an NTSTATUS value. Possible values are the following.
| Value | Description |
|---|---|
STATUS_SUCCESS |
Transmission successful. |
STATUS_DEVICE_PROTOCOL_ERROR |
The card did not return a T=0 status word. |
STATUS_BUFFER_TOO_SMALL |
The user buffer is too small to hold the data. |
Remarks
The driver must store the data coming from the reader into the Buffer member of the SmartcardReply member of the structure pointed to by SmartcardExtension and then it must store the number of bytes returned from the card into the BufferLength member of the SmartcardReply member of this structure. SmartcardT0Reply then checks the validity of the data and copies the buffer back to the user buffer, including the protocol header. See SmartcardT0Request for sample code.
