SysIntLevel (FUN) ¶ FUNCTION SysIntLevel : RTS_IEC_RESULT <description> This function checks if the processor is actually executing an ISR. This information is necessary, as some functions of an operating system must not be called within the interrupt level. </description> <result><p>RESULT: Returns the runtime system error code (see CmpErrors.library): <ul> <li>ERR_OK: We are still in an interrupt handler</li> <li>ERR_FAILED: not in interrupt context</li> </ul> </p></result> InOut: Scope Name Type Return SysIntLevel RTS_IEC_RESULT

SysMemAllocData (FUN) ¶ FUNCTION SysMemAllocData : POINTER TO BYTE Allocates data memory of the specified size RETURN: Pointer to the memory block. 0 if no memory is not available InOut: Scope Name Type Comment Return SysMemAllocData POINTER TO BYTE Input szComponent STRING Can be the library- or POU-name from IEC udiSize __XWORD Requested size of the memory block pResult POINTER TO RTS_IEC_RESULT Pointer to runtime system error code (see CmpErrors_Itfs.library)

SysMemCmp (FUN) ¶ FUNCTION SysMemCmp : DINT Compares the content of two buffers RETURN: Returns 0 if the buffer contents are equal, else !=0 InOut: Scope Name Type Comment Return SysMemCmp DINT Input pBuffer1 POINTER TO BYTE Address of first memory area (buffer 1) pBuffer2 POINTER TO BYTE Address of second memory area (buffer 2) udiCount __XWORD Number of bytes to be compared

SysMemCpy (FUN) ¶ FUNCTION SysMemCpy : POINTER TO BYTE Copy the content from source (pSrc) to destination buffer (pDest) RETURN: Pointer to the destination buffer, where the copy was done InOut: Scope Name Type Comment Return SysMemCpy POINTER TO BYTE Input pDest POINTER TO BYTE Pointer to memory address to be copied to (target) pSrc POINTER TO BYTE Pointer to memory address to be copied from (source) udiCount __XWORD Number of bytes to be copied

SysMemForceSwap (FUN) ¶ FUNCTION SysMemForceSwap : DINT Routine to force swapping memory independant of the byteorder of the system! RETURN: Number of bytes swapped: -1 = failed (size too large) >0 = Number of bytes swapped InOut: Scope Name Type Comment Return SysMemForceSwap 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
