RtecatReadAxisOutputByte reads a byte from an output buffer of an axis.

Syntax

Copy

RTECAT_ERROR RtecatReadAxisOutputByte(
  [in]    RTECAT_HANDLE Axis,
  [in]    ULONG ByteOffset,
  [out]   BYTE* pValue
);

Parameters

[in] Axis

A handle to an axis. To retrieve the corresponding handle, use RtecatOpenAxisByIndex or RtecatOpenAxisByLocation.

[in] ByteOffset

A byte offset to the location to read a BYTE value.

[out] pValue

A pointer to a variable that stores a BYTE from an output buffer of an axis.

Return Values

The function returns an RTECAT_ERROR value. If the function succeeds, it returns ecatErrNoError. If the function fails, it returns a different value.

Possible return values:

Return value	Meaning
ecatErrNoError	The function succeeded.
ecatErrNullParameter	Parameter pValue is NULL.
ecatErrWrongParameter	Parameter Axis or ByteOffset is invalid.
ecatErrMainDeviceNotReady	The MainDevice is not ready.
ecatErrWrongEnvironment	The link has not started.

Remarks

RtecatReadAxisOutputByte is a synchronous function that executes immediately and returns a result upon completion.
