[in] volatile ULONG *Register,
[in] PULONG Buffer,
[in] ULONG Count
);
Parameters
[in] Register
Pointer to the register, which must be a mapped range in memory space.
[in] Buffer
Pointer to a buffer from which an array of ULONG values is to be written.
[in] Count
Specifies the number of ULONG values to be written to the register.
Return value
