[OS_Process->ReadError] reads any available data from the standard error output of the native process and returns a byte stream. This tag accepts one parameter which specifies the maximum number of bytes of data to retrieve. The method will return all available data up to that number of bytes. By default all available data will be retrieved.
No character set translation is performed on the output of this method. A raw byte stream is always returned.
