This function writes a specified number of USHORTvalues from a caller-supplied buffer to a given I/O port.
VOID NdisRawWritePortBufferUshort( IN ULONG Port , IN PUSHORT Buffer , IN ULONG Length );
Parameters
- Port
- Specifies the I/O port. This address falls in a range that was mapped during initialization with the NdisMRegisterIoPortRangefunction.
- Buffer
- Pointer to a caller-allocated resident buffer containing the USHORTs to be written.
- Length
- Specifies the number of
USHORTs to write to the I/O port.
Remarks
An NIC driver calls this function to transfer a sequence of USHORTs, one at a time, to its NIC.
This function runs significantly faster than the NdisImmediateWritePortBufferUshortfunction because it need not map a bus-relative port address onto a host-dependent logical port address at every call.
A driver that calls this function can run at any IRQL.
Requirements
Runs on Versions Defined in Include Link to Windows CE OS 2.0 and later Ndis.h 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.
