A char buffer to store the queried value in.
value_len_bytes
Maximum size of the provided value_str buffer in bytes.
actual_value_len
The size of buffer in value_str actually used to store the queried value.
LV_SUCCESS
No errors.
LV_INVALID_TTS_HANDLE
The TTS client handle is invalid (either Initialize has not been called or Destroy has already been called). Only returned if target is set to PROP_EX_TARGET_PORT.
LV_INVALID_PROPERTY
The specified property is invalid.
LV_INVALID_PROPERTY_TARGET
The specified property is not valid as a global setting.
LV_EXCEPTION
An exception occured while processing the request.
If value_str is set to NULL or value_len_bytes is set to zero, no copying is performed and on a successful return, the value returned in actual_value_len indicates the total size of value_str required to completely store the queried value.
