gen_server:call(xx2, {i_am_at, Person, Location}, 10000) For communication purposes, xx2 is the name of the server and must agree with the name used to start the server. {i_am_at, Person, Location} is a command which is passed to the server, and 10000 is a timeout value.

Semaphore functionality implemented using a gen_server - cobusc/erlang_semaphore 在阅读erlang的otp源码gen_server.erl的时候，一直想写点什么，用一种最好的方式表达出来，最终却总是没法表达清楚，困惑之余看到这篇文章，作者用图解的方式，非常清晰明了的表达了我一直想表达的东西，下面是原文链接： Poolboy - A hunky Erlang worker pool factory. Poolboy is a lightweight, generic pooling library for Erlang with a focus on simplicity, performance, and rock-solid disaster recovery. Usage 1> Worker = poolboy:checkout(PoolName). <0.9001.0> 2> gen_server:call(Worker, Request). ok 3> poolboy:checkin(PoolName, Worker). ok Example Distributed Erlang nodes provide a high-level model for integrating other languages with Erlang programs. With tinch++, your C++ code will be able to communicate with Erlang processes by means of message passing.

Gen_server is a great way to create simple servers without having to write a lot of code at all. Here’s a brief overview to get you started.For some reason, figuring out how the gen_server behavior works in erlang was kind of a pain for me. I think it’s because I can’t just implement something, I …
