Flushing of an output stream handled by the stream itself


is there any class in GLib, GIO etc. which provides automatic content
flushing (e.g. an output stream associated with a socket) that would be
fully asynchronous, working in "background" and would accept multiple
subsequent write requests without risk of blocking?

The g_output_stream_write_async() documentation mentions that "During an
async request no other sync and async calls are allowed, and will result
in G_IO_ERROR_PENDING errors"[1]. So it looks like I have to gather the
result using g_output_stream_write_finish() after every write_async

For example, libevent has evbuffers[2] which accept multiple subsequent
write requests and flush data to a socket internally in the library's
event loop.

Is there anything like evbuffers in GLib/GIO or do I have to implement
it myself? Should I implement it using some kind of queue and manage one
async write request at a time?
