Michael Brown adf6c8e2a6 Add our own trivial version of stdarg.h. This makes our build 
entirely self-hosted (which avoids problems when building the same
tree on multiple systems - e.g. when you have /home NFS-mounted).

Also saves around 50 bytes in total - not sure why.

Michael Brown 070c55a838 Added EPIPE description. 2007-05-26 15:05:31 +00:00
Michael Brown b8618d76db Modify data-xfer semantics: it is no longer necessary to call one of 
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own
process), or otherwise arrange to be called.  TCP does this by
starting the retry timer immediately.

Add some debugging statements.

from the normal POSIX-style open()
 2007-05-18 14:16:06 +00:00
Michael Brown b1755462ab Do not hold self-references. This then avoids the problem of having to 
ensure that we only drop our self-reference exactly once.

To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.
