blocking i/o not implemented for asio (committed needs testing see #148)

ReadStream and WriteStream are not implemented for ASIO. It is necessary to set up separate ring buffers to implement this. If the Read or Write functions were blocked waiting to input or output data to the FIFOs the ASIO callback could set an event/condition variable to wake them up.

There is now a new ticket covering testing this:

#148 -- ASIO blocking i/o implementation needs testing

Sven Fischer from Institute of Hearing Technology and Audiology (IHA) http://www.hoertechnik-audiologie.de has sent in a patch for this (attached to this ticket). I'm working on merging it.

Progress made. I've just checked in a version of Sven's patch to allow the standard portaudio ringbuffer to handle multi-byte elements. see r1346

I have a final patch from Sven. I just need to merge and review it. No reason why this shouldn't go in before RC1

Checked in Sven Fischer's implementation of this in r1363

Still need to ensure we havn't broken the build systems too much. Waiting for some feedback and testing.

The following build files still need to be updated to included pa_ringbuffer.c

The blocking API needs to be estensively tested QAed.

Code review is needed for ReadStream, WriteStream, GetStreamReadAvailable, GetStreamWriteAvailable in pa_asio.cpp.
