ZeroMemory macro
Fills a block of memory with zeros.
To avoid any undesired effects of optimizing compilers, use the SecureZeroMemory function.
Syntax
void ZeroMemory(
[in] PVOID Destination,
[in] SIZE_T Length
);
Parameters
Destination [in]
A pointer to the starting address of the block of memory to fill with zeros.Length [in]
The size of the block of memory to fill with zeros, in bytes.
Return value
This macro has no return value.
Remarks
Many programming languages include syntax for initializing complex variables to zero. There can be differences between the results of these operations and the ZeroMemory function. Use ZeroMemory to clear a block of memory in any programming language.
This macro is defined as the RtlZeroMemory macro. For more information, see WinBase.h and WinNT.h.
