Previous message (by thread): [erlang-questions] gen_tcp send blocks gen_tcp recv. gen_icmp aspires to be a simple interface for using ICMP sockets in Erlang, just like gen_tcp and gen_udp do for their protocol types; incidentally messing up Google searches for whomever someday writes a proper gen_icmp module. [erlang-questions] gen_tcp very slow to fetch data Joe Armstrong erlang@REDACTED Mon Nov 23 16:39:18 CET 2009. Previous message (by thread): [erlang-questions] gen_tcp very slow to fetch data For sockets, we first have to traverse gen_tcp which yields the parsing of packet options to inet.erl, which quickly calls into prim_inet which constructs the actual port commands to the inet_drv port.

Generic TCP Server (gen_tcp_server) is an Erlang behaviour providing quick and easy way to add TCP server functionality to you application.It's implemented as a supervisor managing TCP connections as it's children. Erlang/OTP. Contribute to erlang/otp development by creating an account on GitHub. Erlang gen tcp packet option.

OTP 22 has just been released. It has been a long process with three release candidates before the final release. We decided this year to try to get one month more testing of the major release and I think that the extra time has paid off. We’ve received many bug reports from the community about large and small bugs that our internal tests did not find.

Looking around, I’ve found some interesting libraries, or articles. The best one being probably (and not only for this case, but for all of Erlang), Learn you some Erlang.

Now that we have valid inputs, let's look into Erlang's gen_tcp module - we'll use the listen/2 function to listen for connections. It's declared as such: listen(Port

client() -> SomeHostInNet = "localhost", % to make it runnable on one machine { ok, Sock } = gen_tcp:connect( SomeHostInNet, 5678, [ binary, { packet, 0}]), ok = gen_tcp:send( Sock, "Some Data"), ok = gen_tcp:close( Sock). 在另一端，服务器正在侦听端口5678，接受连接并接收二 Introduction. I have found a race condition in how gen_tcp:controlling_process (which calls inet:tcp_controlling_process) does handoff in a situation where the child process is not barrier synchronized with the parent. 2009-03-26 · gen_tcp:close(Socket). In the above code snipper (from the above mentioned blog), it is to be noted that after getting the connection via gen_tcp:accept/1, a process is spawned to continue listen on the socket and the client is served from the same process unlike in any other language where a thread is spawned to serve the incoming client request and main thread continue to listen on the socket. [erlang-questions] Can gen_tcp/inets store connection-specific user state? Showing 1-16 of 16 messages Over the past years, I noticed a lot of applications implementing asynchronous accept routines for tcp and ssl sockets, by either using the internal (and therefore, subject to possible unannounced breaking changes) prim_inet:async_accept function, or by running the respective accepts in spawned processes, inventing the wheel over and over.
