SmartcardRawReply (WDM) routine

2017-08-16

The SmartcardRawReply routine transfers the data that was received from the smart card to the user buffer.

Syntax

NTSTATUS SmartcardRawReply(
   PSMARTCARD_EXTENSION SmartcardExtension
);

Parameters

SmartcardExtension
A pointer to a SMARTCARD_EXTENSION structure that contains the device extension of the smart card device.

Return value

SmartcardRawReply returns one of the following NTSTATUS values:

Return code	Description
STATUS_SUCCESS	The transmission was successful.
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 SmartcardExtension->SmartcardReply.Buffer, and it must store the number of bytes that the card returned into SmartcardExtension->SmartcardReply.BufferLength. SmartcardRawReply then checks the validity of the data and copies the buffer, which includes the protocol header, back to SmartcardExtension->SmartcardReply.Buffer.

Requirements

Target platform	Desktop
Version	Available in Windows XP and later versions of Windows.
Header	Smclib.h (include Smclib.h)
Library	Smclib.lib
IRQL	<= DISPATCH_LEVEL
