NdisReadRegisterUchar (Compact 2013)

3/26/2014

The network adapter driver to read a UCHAR from a memory-mapped device register calls this function.

Syntax

VOID NdisReadRegisterUchar(
  PUCHAR Register,
  PUCHAR Data
);

Register
[in] Points to the memory-mapped register. This virtual address must fall in a range returned by an initialization-time call to NdisMMapIoSpace.

Data
[out] Points to the caller-supplied variable in which this function returns the UCHAR read from Register.

None.

If a driver calls this function, its network adapter's device registers must be mapped to non-cached memory during driver initialization.
