	)

Return stream content up to (but not returning) the next newline.

std::string zypp::str::getline	(	std::istream &	str,
		bool	trim = `false`

std::string zypp::str::receiveUpTo	(	std::istream &	str,
		const char	delim_r,
		bool	returnDelim_r = `false`
	)

Return stream content up to the next ocurrence of delim_r or EOF delim_r, if found, is always read from the stream.

Whether it is also returned in the string depends on returnDelim_r. If the stream status is good, delim_r was found in the stream. If we reached EOF while looking for delim_r, eof is set; and also fail, if we did not read any data before.

Split line_r into words with respect to escape delimeters.

Any sequence of characters in sepchars_r is treated as delimiter if not inside "" or '' or escaped by .

A non-quoted backslash () preserves the literal value of the next character.
Enclosing characters in single quotes preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash.
Enclosing characters in double quotes preserves the literal value of all characters within the quotes, with the exception of . The backslash retains its special meaning only when followed by " or .

The words are passed to OutputIterator result_r.
