Compare (FUN)¶

FUNCTION Compare : UINT

Function compares “MemoryBlockA” with “MemoryBlockB”. Up to “uiNumberOfBytes” will be compared.

Example:

abyMemoryBlockA : ARRAY[0..9] OF BYTE := 0,1,2,3,4,5,6,7,8,9 ;
abyMemoryBlockB : ARRAY[0..9] OF BYTE := 0,1,2,0,4,5,6,7,8,9 ;
->
MEM.Compare(ADR(abyMemoryBlockA),ADR(abyMemoryBlockB),10) = 4

InOut:

Scope	Name	Type	Comment
Return	`Compare`	`UINT`	function return 0 if the blocks are identical. If they are different then function returns the first position that differ
Input	`pMemoryBlockA`	POINTER TO BYTE	address of MemoryBlockA
	`pMemoryBlockB`	POINTER TO BYTE	address of MemoryBlockB
	`uiNumberOfBytes`	`UINT`	number of bytes to compare
