std::string xmppd::lwresc::lwresult::read_qname

(

std::istream &

is

)

[static]

read a qname (sequence of labels, terminated by a zero label)

Note:

this method does not unread anything if it could not read the string successfully

Parameters:

is

the stream to read from

Returns:

the string that has been read

Exceptions:

std::runtime_error

if no string was readable

std::string xmppd::lwresc::lwresult::read_string

(

std::istream &

is

)

[static]

read a string (16 bit length field, string, zero byte)

Note:

this method does not unread anything if it could not read the string successfully

Parameters:

is

the stream to read from

Returns:

the string that has been read

Exceptions:

std::runtime_error

if no string was readable
