The SmartcardRawRequest function copies data from the user buffer to the send buffer that the driver uses to transmit data to the reader.
Syntax
NTSTATUS SmartcardRawRequest(
PSMARTCARD_EXTENSION SmartcardExtension
);
Parameters
- SmartcardExtension
[in] Points to the smart card extension of the device.
Return Value
SmartcardRawRequest returns an NTSTATUS value. Possible values are the following.
| Value | Description |
|---|---|
STATUS_SUCCESS |
Buffer successfully set up. |
STATUS_BUFFER_OVERFLOW |
The internal buffer is too small to hold the data to send to the smart card. To fix this error, allocate a larger send buffer. See SmartcardInitialize for details. |
STATUS_BUFFER_TOO_SMALL |
The user buffer is too small to hold the data. |
Remarks
This function copies data from the user buffer to the Buffer member of the SmartcardRequest member of the SMARTCARD_EXTENSION structure pointed to by SmartcardExtension, and adjusts the value in the BufferLength member of the SmartcardRequest member of this structure to the number of bytes to be transmitted to the smart card. The driver then simply writes this buffer to the card and reads the bytes coming from the card into the Buffer member of the SmarcardReply member of this structure, as described in SmartcardRawReply.
