/**
 * Retrieves the output (stdout) of the process represented by the given {@link Process}
 * object. This method blocks until the process is about to terminate and returns the
 * complete output as a string. The returned string contains newlines after each output
 * line. This is also true for the last line and for processes that do not output line
 * endings, i.e., the string always has a trailing newline except for empty outputs.
 * Note that the process is likely to have not terminated yet after this method returns.
 * //from   w  ww.j  a va  2  s  . c o  m
 * @param proc
 *          The process object.
 * @return The stdout output of the process. May be an empty string. The string always
 *         has a trailing newline if it is not empty.
 * @throws IOException
 *           If the process output cannot be read.
