Hi
<BR>
<P>I'm currently thinking about using POSIX threads to implement asynchronous
<BR>
I/O in my backend. Most backends that currently implement asynchronous
<BR>
I/O do so by creating a pipe and fork()ing a reader process. Since this
<BR>
already requires POSIX support (pipe(), fork()), requiring pthreads for
<BR>
a backend should not be much of a problem? The backend could fall back
<BR>
to simple synchronous I/O if pthreads are not available (check at
<BR>
compile-time).
<BR>
<P>Regards,
<BR>
Ingo
