);
Parameters

The destination of the operation.
[in] Source
The source of the operation.

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 Dest 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");
}
