This function reads a specified number of bytes into a caller-supplied buffer.
VOID NdisRawReadPortBufferUchar( IN ULONG Port , OUT PUCHAR 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 buffer, in resident memory, into which the bytes are transferred from the NIC's port. The caller must allocate a buffer at least sizeof(Length ).
- Length
- Specifies how many bytes to transfer from the NIC.
Remarks
This function reads each byte, one at a time, from the specified I/O port into the specified buffer.
A driver that calls this function can run at any IRQL.
