RtlEqualMemory macro (wdm.h)

The RtlEqualMemory routine compares two blocks of memory to determine whether the specified number of bytes are identical.

Syntax

BOOL WINAPI
RtlEqualMemory(
   [in] void*  Destination,
   [in] void*  Source,
   [in] size_t Length
);

Parameters

Destination

A pointer to a caller-allocated block of memory to compare.

Source

A pointer to a caller-allocated block of memory that is compared to the block of memory to which Source1 points.

Length

Specifies the number of bytes to be compared.

Return value

RtlEqualMemory returns TRUE if Source1 and Source2 are equivalent; otherwise, it returns FALSE.

Remarks

RtlEqualMemory begins the comparison with byte zero of each block.

Callers of RtlEqualMemory can be running at any IRQL if both blocks of memory are resident.
