RtecatReadSubDeviceEEprom

RtecatReadSubDeviceEEprom reads a double word from a SubDevice's EEPROM.

Syntax

Copy

RTECAT_COMMAND_STATUS RtecatReadSubDeviceEEprom(
  [in]    RTECAT_HANDLE SubDevice,
  [in]    ULONG Offset,
  [out]   DWORD* pData
);

Parameters

[in] SubDevice

A handle to a SubDevice. To retrieve the corresponding handle, use RtecatOpenSubDeviceByIndex, RtecatOpenSubDeviceByStationAddress, or RtecatOpenSubDeviceByExplicitId.

[in] Offset

The offset in the EEPROM space.

[out] pData

A pointer to a variable that stores the data from a SubDevice's EEPROM.

Return Values

The function returns an RTECAT_COMMAND_STATUS structure. If an error occurs, field State of the structure is set to ecatCommandError and the error code is stored in field ErrorId (see RTECAT_ERROR for error values). If the function succeeds, ErrorId is set to ecatErrNoError (which is represented by the value 0). If the function fails, it stores a different error value.

Possible return values:

Return value	Meaning
ecatErrNoError	The function succeeded.
ecatErrNullParameter	Parameter pData is NULL.
ecatErrWrongParameter	Parameter SubDevice is invalid.
ecatErrWrongEnvironment	The EEPROM requesting channel is occupied.
ecatErrMainDeviceNotReady	The MainDevice is not ready.

Remarks

RtecatReadSubDeviceEEprom is an asynchronous function that takes time to complete. It allows for background execution and requires you to check its status by calling RtecatGetCommandStatus or wait for it to complete by calling RtecatWaitForCommand.
