Erlang源代码编译为beam文件,代码要经过一系列的过程(见下面的简图),Core Erlang之前已经简单介绍过了Core Erlang,代码转换为Core Erlang,就容易拨开一些语法糖的真面目了.下一阶段就是将Core Erlang转换为opcode,使用c(m,'S')生成的是.S文件可以看到反编译的代码.编译器最终输出的是Virtua

When an Erlang function compiled to C is called, the next instruction pointer, I, is stored in the current local frame and the CP pointer is set to the emulator code which would restore the I pointer upon return from the called function. 2.2 Data Objects Erlang (אֶרְלַנְג) היא שפת תכנות כללית ופונקציונלית אשר נוצרה על ידי מדעני המחשב ג'ו ארמסטרונג, רוברט וירדינג, ומייק ויליאמס ושוחררה לראשונה בשנת 1986.Erlang תומכת הן בתכנות פונקציונלי והן בתכנות מקבילי ולפיכך נחשבת לשפה Technique for running Erlang NIFs functions asynchronously, not on scheduler threads. - async_nif.h How to implement a resettable countdown timer using GenServer in Elixir or Erlang.

Encodes a reference object (an object generated with erlang:make_ref/0). The Node term is an encoded atom, that is, ATOM_EXT , SMALL_ATOM_EXT , or ATOM_CACHE_REF . The ID field contains a big-endian unsigned integer, but is to be regarded as uninterpreted data , as this field is node-specific.

Pids There can be at most one service with a given name on a given node. Note that erlang:make_ref/0 can be used to generate a service name that is somewhat unique. service_opt() Option passed to start_service/2. Can be any capability() as well as the following. {application, [application_opt()]} A Diameter application supported by the service.

The native implemented functions Makes a pid term from *pid. ERL_NIF_TERM enif_make_ref(ErlNifEnv* env) Creates a reference like erlang: make_ref/0. Call a given built-in function (the function cannot fail). can be the following: CurrentNode - node/0; Self - self/0; MakeRef - make_ref/0; Gleader  Такой подход выбрали и Joe Armstrong (Programming Erlang, глава 16), и Fred Hebert (LYSE, глава What is OTP?).
