PDCARD_SOCKET_STATE

  • Article

This structure is used by the PDCardGetSocket and PDCardSetSocket functions to retrieve or change the specified socket's characteristics.

typedef struct {
  UINT8 fSocketCaps;
  UINT8 fInterruptEvents;
  UINT8 fNotifyEvents;
  UINT8 fControlCaps;
  UINT8 fInterfaceType;
  UINT8 fIREQRouting;
  UINT8 fVcc;
  UINT8 uVpp1;
  UINT8 uVpp2;
} PDCARD_SOCKET_STATE;

Members

  • fSocketCaps
    Specifies socket capabilities.

  • fInterruptEvents
    Specifies a status change interrupt mask. The initial state of this member indicates which events can cause a status change interrupt. The events are shown in the following table.

    Event mask Description
    EVENT_MASK_WRITE_PROTECT Write-protect state
    EVENT_MASK_CARD_LOCK Card lock state
    EVENT_MASK_EJECT_REQ Ejection request
    EVENT_MASK_INSERT_REQ Insertion request
    EVENT_MASK_BATTERY_DEAD Battery dead
    EVENT_MASK_BATTERY_LOW Battery low
    EVENT_MASK_CARD_READY Ready change
    EVENT_MASK_CARD_DETECT Card detect
    EVENT_MASK_POWER_MGMT Power management change
    EVENT_MASK_RESET Card reset
    EVENT_MASK_STATUS_CHANGE Card-generated status change interrupt

  • fNotifyEvents
    Specifies latched socket state. The events are shown in the following table.

    Event mask Description
    EVENT_MASK_WRITE_PROTECT Write-protect state
    EVENT_MASK_CARD_LOCK Card lock state
    EVENT_MASK_EJECT_REQ Ejection request
    EVENT_MASK_INSERT_REQ Insertion request
    EVENT_MASK_BATTERY_DEAD Battery dead
    EVENT_MASK_BATTERY_LOW Battery low
    EVENT_MASK_CARD_READY Ready change
    EVENT_MASK_CARD_DETECT Card detect
    EVENT_MASK_POWER_MGMT Power management change
    EVENT_MASK_RESET Card reset
    EVENT_MASK_STATUS_CHANGE Card-generated status change interrupt

  • fControlCaps
    Control capabilities.

  • fInterfaceType
    Specifies memory-only or memory and I/O.

  • fIREQRouting
    Enable or disable IREQ.

  • fVcc
    Vcc power entry index and status.

  • uVpp1
    Vpp1 power entry index into a PDCARD_POWERENTRY array that is returned by PDCardInquireAdapter.

  • uVpp2
    Vpp2 power entry index into a PDCARD_POWERENTRY array that is returned by PDCardInquireAdapter.

Remarks

It supports the implementation of the driver described in the sample PC Card socket driver.

The EVENT_MASK_POWER_MGMT, EVENT_MASK_RESET and EVENT_MASK_STATUS_CHANGE event masks should not be generated by the socket itself, that is, they will not fit in the fInterruptEvent and the fNotifyEvents members of the PDCARD_SOCKET_STATE structure.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Sockserv.h.
