__movsq
Microsoft Specific
Generates a repeated Move String (rep movsq) instruction.
Syntax
void __movsq(
unsigned long long* Destination,
unsigned long long const* Source,
size_t Count
);
Parameters
Destination
[out] The destination of the operation.
Source
[in] The source of the operation.
Count
[in] The number of quadwords to copy.
Requirements
| Intrinsic | Architecture |
|---|---|
__movsq |
x64 |
Header file <intrin.h>
Remarks
The result is that the first Count quadwords pointed to by Source are copied to the Destination string.
This routine is only available as an intrinsic.
Example
// movsq.cpp
// processor: x64
#include <stdio.h>
#include <intrin.h>
#pragma intrinsic(__movsq)
int main()
{
unsigned __int64 a1[10];
unsigned __int64 a2[10] = {950, 850, 750, 650, 550, 450, 350, 250,
150, 50};
__movsq(a1, a2, 10);
for (int i = 0; i < 10; i++)
printf_s("%d ", a1[i]);
printf_s("\n");
}
950 850 750 650 550 450 350 250 150 50
