[Boost-users] ASIO ssl::stream read/write_some question.

Could someone please shed some light on ASIO SSL reads and writes for me?
The names of the read and write functions for the ssl::stream (read_some and
write_some) imply to me that the buffer(s) may not be completely filled/sent
with a read/write. Do I need to have some intermediate handler that will
begin another async_read/write_some until my buffer is filled/flushed? The
documentation doesn't seem to indicate that this is necessary. It makes
sense from the example that the reads may not fill the provided buffer
before invoking the handler. So it may be necessary to call read_some
multiple times until the expected number of bytes is received. But is this
also the case with writes, and if so, how do I manage multiple writes if I
provide a vector of buffers to be written with and async_write_some?
Thanks in advance.
