* Reads one table of results from the response. Leaves begin pointing at the
* next table.
*/

const nsACString::const_iterator& end)

return NS_OK;
}示例2: PushOverLine
// Reads over a CRLF and positions start after it.
bool

{
if (*aStart == nsCRT::CR && (aStart.size_forward() > 1) && *(++aStart) == nsCRT::LF) {

return true;
}
return false;
