eExecStatus e_potentiometer_get_config

(

signed portCHAR **

ppcStringReply

)

Get the potentiometer sensor config.

Parameters

ppcStringReply

Input/Output. The response string. NEVER NULL AS INPUT. A malloc for the response string is performed here; the caller must free this string.

Returns

the status of the command execution.

	)

Set the sensor config.

Parameters

ppcStringReply	Input/Output. The response string. NEVER NULL AS INPUT.
ac	Input. Number of args
av	Input. pointer to args

Returns

the status of the command execution.
