ZeroMemory

ZeroMemory宏

The ZeroMemory macro fills a block of memory with zeros.
ZeroMemory宏用0來(lái)填充一塊內(nèi)存區(qū)域。

To avoid undesired effects of optimizing compilers, use theSecureZeroMemory function.
為了避免優(yōu)化編譯器的意外的影響，請(qǐng)使用SecureZeroMemory函數(shù)。

void ZeroMemory(
PVOID Destination, //地址
SIZE_TLength //填0的長(zhǎng)度
);

Parameters
參數(shù)：

Destination
[in] Pointer to the starting address of the block of memory to fillwith zeros.
指向一塊準(zhǔn)備用0來(lái)填充的內(nèi)存區(qū)域的開(kāi)始地址。

Length
[in] Size of the block of memory to fill with zeros, inbytes.
準(zhǔn)備用0來(lái)填充的內(nèi)存區(qū)域的大小，按字節(jié)來(lái)計(jì)算。

Return V--alues
返回值：

This function has no return value.
這個(gè)函數(shù)沒(méi)有返回值。

This function is defined as the RtlZeroMemory macro. For moreinformation, see Winbase.h and Winnt.h.
這個(gè)函數(shù)被定義為RtlZeroMemory宏。至于更多信息，請(qǐng)查看Winbase.h與Winnt.h這兩個(gè)頭文件。
