- Writes a 64-bit value to a Machine Specific Register(MSR), and returns the
- value.
-
- Writes the 64-bit value specified by Value to the MSR specified by Index. The
- 64-bit value written to the MSR is returned. No parameter checking is
- performed on Index or Value, and some of these may cause CPU exceptions. The
- caller must either guarantee that Index and Value are valid, or the caller
- must establish proper exception handlers. This function is only available on
- IA-32 and x64.
-
- @param Index The 32-bit MSR index to write.
- @param Value The 64-bit value to write to the MSR.

- @return Value
