NdisRawWritePortBufferUlong (Compact 2013)
3/26/2014
This function writes a specified number of ULONG values from a caller-supplied buffer to a given I/O port.
Syntax
VOID NdisRawWritePortBufferUlong(
ULONG Port,
PULONG Buffer,
ULONG Length
);
Parameters
- Port
[in] Specifies the I/O port. This address falls in a range that was mapped during initialization with the NdisMRegisterIoPortRange function.
- Buffer
[in] Pointer to a caller-allocated resident buffer that contains the ULONGs to be written.
- Length
[in] Specifies the number of ULONGs to write to the I/O port.
Return Value
None.
Remarks
A miniport driver calls NdisRawWritePortBufferUlong to transfer a sequence of ULONGs, one at a time, to a network adapter.
NdisRawWritePortBufferUlong runs fast because it does not have to map a bus-relative port address onto a host-dependent logical port address at every call.
