Description

Name	Description
hWD	Handle to WinDriver's kernel-mode driver as received from `WD_Open`() [5.2]
pPcmciaCard	Pointer to a PCMCIA card information structure:
• PcmciaSlot	PCMCIA slot information structure:
* uBus	Bus number (0 based)
* uSocket	Socket number (0 based)
* uFunction	Function number (0 based)
• Card	Card information structure:
* dwItems	Number of items detected on the card
* Item	Card items information structure:
• item	Type of item. Can be `ITEM_MEMORY`, `ITEM_IO`, `ITEM_INTERRUPT` or `ITEM_BUS`.
• fNotSharable	1 — Non-sharable resource; should be locked for exclusive use 0 — Sharable resource Note: You can modify the value of this field before registering the card and its resources using `WD_CardRegister`() [2.8].
• I	Specific data according to the `item` type:
* Mem	Describes a memory item (`item = ITEM_MEMORY`):
• dwPhysicalAddr	First address of the physical memory range
• dwBytes	Length of the memory range, in bytes
• dwBar	Base Address Register (BAR) number of the memory range
* IO	Describes an I/O item (`item = ITEM_IO`):
• dwAddr	First address of the I/O range
• dwBytes	Length of the I/O range, in bytes
• dwBar	Base Address Register (BAR) number for the I/O range
* Int	Describes an interrupt item (`item = ITEM_INTERRUPT`):
• dwInterrupt	Physical interrupt request (IRQ) number
• dwOptions	Interrupt options bit-mask, which is set by the function to indicate the interrupt types supported by the device. PCMCIA interrupts are edge triggered, therefore the function sets the `INTERRUPT_LATCHED` flag (value zero), which when used alone (i.e., when no other flag is set) indicates that the hardware uses legacy edge-triggered interrupts.
* Bus	Describes a bus item (`item = ITEM_BUS`):
• dwBusType	The card's bus type. For a PCMCIA card the bus type is `WD_BUS_PCMCIA`
• dwBusNum	The card's bus number
• dwSlotFunc	A combination of the card's bus socket and function numbers: the lower three bits represent the function number and the remaining bits represent the socket number. For example: a value of 0x80 (<=> 10000000 binary) corresponds to a function number of 0 (lower 3 bits: 000) and a socket number of 0x10 (remaining bits: 10000).
• cVersion	Card version string
• cManufacturer	Card manufacturer string
• cProductName	Card product name string
• wManufacturerId	Card manufacturer ID
• wCardId	Card type and model ID
• wFuncId	Card function ID
• dwOptions	Should always be set to 0 (reserved for future use)

Return Value

Returns WD_STATUS_SUCCESS (0) on success, or an appropriate error code otherwise [A].

Remarks

Resource information for PCMCIA cards is obtained by WinDriver from the Windows Plug-and-Play Manager.

Example

WD_PCMCIA_CARD_INFO pcmciaCardInfo;
WD_CARD Card;

BZERO(pcmciaCardInfo);
pcmciaCardInfo.pcmciaSlot = pcmciaSlot;
WD_PcmciaGetCardInfo(hWD, &pcmciaCardInfo);
if (pcmciaCardInfo.Card.dwItems!=0) /* At least one item was found */
{
    Card = pcmciaCardInfo.Card;
}
else
{
    printf("Failed fetching PCMCIA card information\n");
}
