PDCardWriteAttrByte

  • Article

This function writes a byte to the specified offset in a card's attribute memory space.

VOID PDCardWriteAttrByte(
  PVOID pCardMem,
  UINT32 uOffset,
  UINT8 uByte 
);

Parameters

  • pCardMem
    [in] Pointer to PC Card attribute memory obtained from the CardMapMemory function.
  • uOffset
    [in] Integer setting the offset into card's attribute memory.
  • uByte
    [in] Specifies the byte to be written.

Return Values

None.

Remarks

This function is called within a try-except statement in case the card is removed and the memory access results in a fault.

Some modem cards show problems related to reading their configuration information soon after power has been applied to the PCMCIA bus, which can cause a Windows CE-based platform to stop responding until the card is removed. If you are writing a device driver for a PCMCIA-Card based modem that is showing this behavior, insert a call to Sleep(1) between the driver's call to PcmciaPowerOn and the first call to PDCardWriteAttrByte.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Sockserv.h.
Link Library: Cardserv.lib.
