__movsd

  • Cikk

Microsoft Specific

Generates a Move String (rep movsd) instruction.

Syntax

void __movsd(
   unsigned long* Destination,
   unsigned long* Source,
   size_t Count
);

Parameters

Destination
[out] The destination of the operation.

Source
[in] The source of the operation.

Count
[in] The number of doublewords to copy.

Requirements

Intrinsic Architecture
__movsd x86, x64

Header file <intrin.h>

Remarks

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

This routine is only available as an intrinsic.

Example

// 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]);
    printf_s("\n");
}

950 850 750 650 550 450 350 250 150 50
