# Function Reference

# _WinAPI_EqualMemory

Compares two blocks of memory to determine whether the specified number of bytes are identical

#include <WinAPIMem.au3>
_WinAPI_EqualMemory ( $pSource1, $pSource2, $iLength )

## Parameters

$pSource1 | A pointer to the block of memory to compare.
$pSource2 | A pointer to the block of memory that is compared to the block of memory to which $pSource1 points.
$iLength | The number of bytes to be compared.

## Return Value

Success: | 1 - The two memory blocks are equivalent.
Failure: | 0 and sets the @error flag to non-zero.

## Example

    #include <WinAPIMem.au3>

    Local $tStruct1 = DllStructCreate('byte[8]')
    Local $tStruct2 = DllStructCreate('byte[8]')

    _WinAPI_FillMemory($tStruct1, 8, 0x1D)
    _WinAPI_FillMemory($tStruct2, 8, 0x1D)

    ConsoleWrite('Two structures are equivalent: ' & _WinAPI_EqualMemory($tStruct1, $tStruct2, 8) & @CRLF)
