`SyncWriteVars` (FUN)

FUNCTION SyncWriteVars : Error

Writes the given list of values synchronously to the given list of variables.

Important

As communication and symbolic resolution is involved, take care (async calls etc.) when using this method from an IEC-Task

InOut:

Scope	Name	Type	Comment
Return	`SyncWriteVars`	Error	An errorcode representing the result of this operation
Input	`hPlcHandler`	`SysTypes.RTS_IEC_HANDLE`	The instance of the PLCHandler to work on.
	`ppInstPaths`	POINTER TO POINTER TO BYTE	A POINTER to an ARRAY of POINTERs to zero terminated ASCII STRINGs representing the instance paths that should be written
	`ppValues`	POINTER TO POINTER TO BYTE	A POINTER to an ARRAY of POINTERs to the values that should be written.
	`pulSizes`	POINTER TO UDINT	An optional POINTER to an ARRAY of sizes of each item. If omitted, the performance of the write operation might not be optimal because the according information has to be derived from the internal symbol tables.
	`numVars`	`UDINT`	The number of variables to write. In fact this number represents the sizes of the arrays given by `ppInstPaths`, `ppValues` and `pulSizes` so all three arrays are expected to have the same size.
