__movsw

  • Article

Microsoft Specific

Generates a Move String (rep movsw) instruction.

Syntax

void __movsw(
   unsigned short* Destination,
   unsigned short* Source,
   size_t Count
);

Parameters

Destination
[out] The destination of the operation.

Source
[in] The source of the operation.

Count
[in] The number of words to copy.

Requirements

Intrinsic Architecture
__movsw x86, x64

Header file <intrin.h>

Remarks

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

This routine is only available as an intrinsic.

Example

// movsw.cpp
// processor: x86, x64
#include <stdio.h>
#include <intrin.h>

#pragma intrinsic(__movsw)

int main()
{
    unsigned short s1[10];
    unsigned short s2[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    __movsw(s1, s2, 10);

    for (int i = 0; i < 10; i++)
        printf_s("%d ", s1[i]);
    printf_s("\n");
}

0 1 2 3 4 5 6 7 8 9
