CARD_REGISTER_PARMS

The CARD_REGISTER_PARMS structure contains driver characteristics passed to CardRegisterClient. All members are input only.

Syntax

typedef struct {
UINT16 fAttributes;
UINT16 fEventMask;
UINT32 uClientData;
} CARD_REGISTER_PARMS, *PCARD_REGISTER_PARMS;

Members

fAttributes

A bitmask of the following flags:

CLIENT_ATTR_MEM_DRIVER

RAM or SRAM Memory driver

CLIENT_ATTR_MTD_DRIVER

Flash RAM Memory driver, sometimes known as a Memory Technology driver.

CLIENT_ATTR_IO_DRIVER

I/O driver

CLIENT_ATTR_NOTIFY_SHARED

Sharable PC Card

CLIENT_ATTR_NOTIFY_EXCLUSIVE

Exclusively used PC Card

fEventMask

Specifies a global socket events bitmask. See PC Card Event Masks.

uClientData

Specifies 32 bits of context data sent to the client's callback function. This data is usually a pointer to a data structure.

Remarks

The client data (uClientData) is passed as is to the installable device driver's callback function. The client can interpret this context data in any manner it chooses.

CARD_SOCKET_HANDLE

The CARD_SOCKET_HANDLE structure identifies a socket and function pair composed of a socket number and function number.

Syntax

typedef struct {
UINT8 uSocket;
UINT8 uFunction;
} CARD_SOCKET_HANDLE, *PCARD_SOCKET_HANDLE;

Members

uSocket

Specifies the socket number. The first socket is 0 (zero).

uFunction

Specifies the function number on the socket. The first function is 0 (zero).

Remarks

The installable device driver generates these values and uses them in various Card Services functions.

For single function cards, the function number is zero. For multiple function cards, the function number ranges from zero through one less than the number of functions on the card.
