__setReg
Microsoft Specific
Sets the value of a register specified by the first parameter, which are the same values as declared in the header file intrin.h.
void __setReg(
int Register,
unsigned __int64 Value
);
Parameters
- [in] Register
A constant specifying the desired processor register.
- [in] Value
The value to set in the specified register.

Remarks
Attempting to write directly to processor registers can produce unexpected results. Some registers are not writeable in user mode and might throw a hardware exception or ignore attempts to write to them. For more information, see the processor documentation.
This routine is only available as an intrinsic.
Example
// setReg.cpp
// processor: IPF
#include <cstdio>
#include <intrin.h>
#define __CV_IPF_IntR10 1034
#pragma intrinsic(__setReg)
#pragma intrinsic(__getReg)
int main()
{
__setReg(__CV_IPF_IntR10, 167);
printf_s("%I64d\n", __getReg(__CV_IPF_IntR10));
return 0;
}
Output
167
