Microsoft Specific
Generates a store string instruction (rep stosd).
Syntax
void __stosd(
unsigned long* Destination,
unsigned long Data,
size_t Count
);
Parameters
Destination
[out] The destination of the operation.
Data
[in] The data to store.
Count
[in] The length of the block of doublewords to write.
Requirements
| Intrinsic | Architecture |
|---|---|
__stosd |
x86, x64 |
Header file <intrin.h>
Remarks
The result is that the doubleword Data is written into a block of Count doublewords at the memory location pointed to by Destination.
This routine is only available as an intrinsic.
Example
// stosd.c
// processor: x86, x64
#include <stdio.h>
#include <memory.h>
#include <intrin.h>
#pragma intrinsic(__stosd)
int main()
{
unsigned long val = 99999;
unsigned long a[10];
memset(a, 0, sizeof(a));
__stosd(a+1, val, 2);
printf_s( "%u %u %u %u",
a[0], a[1], a[2], a[3]);
}
0 99999 99999 0
