The SmartcardRawRequestfunction copies data from the user buffer to the send buffer that the driver uses to transmit data to the reader.
NTSTATUS SmartcardRawRequest( PSMARTCARD_EXTENSION SmartcardExtension );
SmartcardRawRequestreturns an NTSTATUS value. Possible values are the following:
|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 SmartcardInitializefor details.|
|STATUS_BUFFER_TOO_SMALL||The user buffer is too small to hold the data.|
This function copies data from the user buffer to SmartcardExtension->SmartcardRequest.Bufferand adjusts SmartcardExtension->SmartcardRequest.BufferLengthto 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 SmartcardExtension->SmartcardReply.Buffer, as described in SmartcardRawReply.
