Microsoft Specific**

Generates a Move String (rep movsd) instruction.


void __movsd(   
   unsigned long* Dest,   
   unsigned long* Source,   
   size_t Count   


[out] Dest
The destination of the operation.

[in] Source
The source of the operation.

[in] Count
The number of doublewords to copy.


Intrinsic Architecture
__movsd x86, x64

Header file <intrin.h>


The result is that the first Count doublewords pointed to by Source are copied to the Dest string.

This routine is only available as an intrinsic.


// movsd.cpp  
// processor: x86, x64  
#include <stdio.h>  
#include <intrin.h>  
#pragma intrinsic(__movsd)  
int main()  
    unsigned long a1[10];  
    unsigned long a2[10] = {950, 850, 750, 650, 550, 450, 350,  
                            250, 150, 50};  
    __movsd(a1, a2, 10);  
    for (int i = 0; i < 10; i++)  
        printf_s("%d ", a1[i]);  
950 850 750 650 550 450 350 250 150 50
