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
- Pointer to PC Card attribute memory obtained from the CardMapMemoryfunction.
- uOffset
- Integer setting the offset into card's attribute memory.
- uByte
- Specifies the byte to be written.
Remarks
This function is called within a try-exceptstatement 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 PC-Card based modem that is showing this behavior, insert a call to Sleep(1)between the driver's call to PcmciaPowerOnand the first call to PDCardWriteAttrByte.
Requirements
Runs on Versions Defined in Include Link to Windows CE OS 1.0 and later Note This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
