为什么ZeroMemory被MASM32认为是未声明的？invoke ZeroMemory,eax,SIZEOF ofn

There is no RtlZeroMemory in MSDN

RtlZeroMemory
The RtlZeroMemory routine fills a block of memory with zeros, given a pointer to the block and the length, in bytes, to be filled.

VOID
RtlZeroMemory(
IN VOID UNALIGNED *Destination,
IN SIZE_T Length
);
Parameters
Destination
Pointer to the memory to be filled with zeros.
Length
Specifies the number of bytes to be zeroed.
Return Value
None

Headers
Declared in wdm.h and ntddk.h. Include wdm.h or ntddk.h.

Comments
To zero out a memory buffer to erase security-sensitive data, use RtlSecureZeroMemory instead.

Callers of RtlZeroMemory can be running at any IRQL if the Destination block is in nonpaged pool. Otherwise, the caller must be running at IRQL <= APC_LEVEL.

这个是什么函数?在MSDN中可以找到吗?ZeroMemory是WINDOWS的基础函数,为什么在MASM32的函数库中没有提供?

vc98\include\winbase.h line 99:
#define ZeroMemory RtlZeroMemory

RtlZeroMemory 有2个版本：
vc98\include\winnt.h line:6547

#if defined(_M_AXP64) || defined(_M_IA64)
NTSYSAPI
VOID
NTAPI
RtlZeroMemory (
VOID UNALIGNED *Destination,
SIZE_T Length
);
#else
#define RtlZeroMemory(Destination,Length) memset((Destination),0,(Length))
#endif

其实就是c runtime lib的memset，

声明如下：

memset PROTO C, :DWORD, :SDWORD, :DWORD

再重复一下，RtlZeroMemory 有2个版本：
参考：vc98\include\winnt.h line:6547
