[erlang-questions] Non-blocking for gen_tcp:accept?

[Zhongzheng Liu]

Hi all:

Socket can be set to {active, true} to receive data by message instead
of using gen_tcp:recv.

But there is no {active_accept, true} option to make accept
non-blocking. We have to use the blocking function  gen_tcp:accept,
why?

Is it a good idea to deliver a message like {tcp, accept, Socket} to
the accepting process when a connection is coming?

Thanks
