DWORD |
Address of memory area MemoryBlockB |
|
uiLengthBlockB |
UINT |

MEM.FindBlock |
UINT |
Position of first occurrence, if existent; 0 else. |
Example:
abyMemoryBlockA : ARRAY[0..9] OF BYTE := 0,1,2,3,4,5,6,7,8,9 ;
abyMemoryBlockB : ARRAY[0..2] OF BYTE := 6,7,8 ;
->
MEM.FindBlock(ADR(abyMemoryBlockA),10, ADR(abyMemoryBlockB),3) = 7
