Name:
GIOCTL0A.C (Gemplus IOCTL Smart card Reader module 0A)
Description:
This module holds the IOCTL functions for a smart card reader driver
in compliance with PC/SC.
Environment:
Kernel mode
Revision History :
dd/mm/yy
13/03/98: V1.00.001 (GPZ)
- Start of development.
26/04/98: V1.00.002 (GPZ)
- Add the RestoreCommunication function for the Power Management.
18/06/98: V1.00.003 (GPZ)
- Send a classic PowerUp command (0x12 only) for a Warm reset
in case of the Transparent protocol is selected.
- The functions which use KeAcquireSpinLock/KeAcquireCancelSpinlock
must be NOT PAGEABLE.
28/08/98: V1.00.004 (GPZ)
- Check the size of the output buffers before a RtlCopyMemory.
22/01/99: V1.00.005 (YN)
- Change the way to increase com port speed

Routine Description:
This function is called by the Smart card library when a
IOCTL_SMARTCARD_POWER occurs.
This function provides 3 differents functionnality, depending of the minor
IOCTL value
- Cold reset (SCARD_COLD_RESET),
- Warm reset (SCARD_WARM_RESET),
- Power down (SCARD_POWER_DOWN).
Arguments:
SmartcardExtension - is a pointer on the SmartCardExtension structure of
the current device.
Return Value:
STATUS_SUCCESS - We could execute the request.
STATUS_NOT_SUPPORTED - We could not support the minor Ioctl.
