Return a completion condition function object that indicates that a read or write operation should continue until all of the data has been transferred, or until an error occurs.
unspecified transfer_all();
This function is used to create an object, of unspecified type, that meets CompletionCondition requirements.
Reading until a buffer is full:
boost::array<char, 128> buf;
asio::error_code ec;
std::size_t n = asio::read(
sock, asio::buffer(buf),
asio::transfer_all(), ec);
if (ec)
{
// An error occurred.
}
else
{
// n == 128
}
