gen_server module in Erlang provides the server of a client-server relation. As shown in the graph, the model is usually We report on the analysis of gen_server, a popular Erlang library to build client- server applications.

Its name is gen_server and it has an interface a bit similar to the one we've written with my_server in last chapter; it gives you a few functions to use it and in exchange, your module has to already have a few functions gen_server will use. This behavior is a bit unfortunate because it makes it difficult to write a reliable shutdown procedure for a gen_server process. Also, it is not a good habit to trap exits just for the sake of being able to run terminate/2 , since you might catch a lot of other errors which makes it harder to debug the system. % % Description: Makes an existing process into a gen_server. % % The calling process will enter the gen_server receive % % loop and become a gen_server process. % % The process *must* have been started using one of the % % start functions in proc_lib, see proc_lib(3).
