PCMCIA_SOCKET_INFORMATION structure (ntddpcm.h)

  • Article

The PCMCIA_SOCKET_INFORMATION structure is used in conjunction with the IOCTL_SOCKET_INFORMATION request to retrieve socket configuration and state data.

Syntax

typedef struct _PCMCIA_SOCKET_INFORMATION {
  USHORT Socket;
  USHORT TupleCrc;
  UCHAR  Manufacturer[MANUFACTURER_NAME_LENGTH];
  UCHAR  Identifier[DEVICE_IDENTIFIER_LENGTH];
  UCHAR  DriverName[DRIVER_NAME_LENGTH];
  UCHAR  DeviceFunctionId;
  UCHAR  Reserved;
  UCHAR  CardInSocket;
  UCHAR  CardEnabled;
  ULONG  ControllerType;
} PCMCIA_SOCKET_INFORMATION, *PPCMCIA_SOCKET_INFORMATION;

Members

Socket

Indicates the socket number.

TupleCrc

Contains a 16-bit CRC that is concatenated with the PCMCIA prefix, the manufacturer-name string, the product-name string, and the instance value for the card to produce the device ID for a PC Card or CardBus card. For more information about PCMCIA device IDs, see Identifiers for PCMCIA Devices.

Manufacturer[MANUFACTURER_NAME_LENGTH]

Indicates the manufacturer of the PC Card or CardBus card.

Identifier[DEVICE_IDENTIFIER_LENGTH]

Contains the device ID of the PC Card or CardBus card.

DriverName[DRIVER_NAME_LENGTH]

Contains the name of the PC Card or CardBus card device driver.

DeviceFunctionId

Indicates the type of PC Card or CardBus card. This value can be one of the following.

PC Card Type Meaning
PCCARD_TYPE_MULTIFUNCTION Multifunction card.
PCCARD_TYPE_MEMORY Memory card.
PCCARD_TYPE_SERIAL Serial port card.
PCCARD_TYPE_PARALLEL Parallel port card.
PCCARD_TYPE_ATA Disk controller card.
PCCARD_TYPE_VIDEO Video controller card.
PCCARD_TYPE_NETWORK Network controller card.
PCCARD_TYPE_AIMS Auto-increment mass storage card.
PCCARD_TYPE_SCSI_BRIDGE SCSI bridge card.
PCCARD_TYPE_SECURITY Security card.
PCCARD_TYPE_MULTIFUNCTION3 Multifunction 3.0 PC Card.
PCCARD_TYPE_FLASH_MEMORY Flash memory card.
PCCARD_TYPE_MODEM Modem card.

Reserved

Reserved.

CardInSocket

Indicates that there is a card present in the socket.

CardEnabled

Indicates that the card is enabled.

ControllerType

Indicates the controller type. Some common controller types are defined in the PCMCIA_CONTROLLER_CLASS enumeration.
