convert a wchar_t array to PUNICODE_STRING

Question

I have a const string - "testfilename.sys", and I want to create a PUNICODE_STRING that will hold it.
How can I do that?

Answer 1

As @David Heffernan pointed out, RtlInitUnicodeString is the way to create UNICODE_STRING structures.

In your case:

#include <Winternl.h>

[...]

UNICODE_STRING myUnicodeStr;
RtlInitUnicodeString(&myUnicodeStr, L"testfilename.sys");

A PUNICODE_STRING is just UNICODE_STRING*.
