Microsoft Specific**

Generates a repeated Move String (rep movsq) instruction.

Syntax

void __movsq(   
   unsigned char* Dest,   
   unsigned char* Source,   
   size_t Count   
);  

Parameters

[out] Dest
The destination of the operation.

[in] Source
The source of the operation.

[in] Count
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 Dest 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
