`SysMemSwap` (FUN)

FUNCTION SysMemSwap : DINT

Routine to swap memory into littel endian. If little endian (intel) byteorder is received and platform has big endian (motorola) byteorder. On little endian byteorder platforms, routine does nothing RETURN: Number of bytes swapped:

-1 = failed (iSize too large)

0 = no swapping necessary (little endian byteorder)

>0 = Number of bytes swapped (big endian byteorder)

InOut:

Scope	Name	Type	Comment
Return	`SysMemSwap`	`DINT`
Input	`pbyBuffer`	POINTER TO BYTE	Pointer to data to swap. You can check, which order is selected by calling the routine with pbyBuffer=0
	`udiSize`	`UDINT`	Size of one element to swap
	`udiCount`	`UDINT`	Number of elements to swap
