Atom The atom is equivalent to the enumeration type in C ++, but the value of the atom in Erlang is itself. An atom is a string starting with a lower-case letter. However, if it is enclosed by single quotes, it doesn't matter if it is named. A

Erlang provides binary_to_term to convert binary data into original Erlang data. However, this function also has side effects. If you directly perform a binary_to_term operation on the data transmitted from the peer end, the VM crash may be dropped. Binary_to_term side effects This is because binary_to_term generates these atoms when binary data has Atomic values. However, the total number of VM atoms is li

Create a Emakefile fileAt compile time, the compiler will handle the Emakefile file as appropriate.{[' src/* '% specify the erl source file directory],[debug_info,{i, "include"} percent specifies the Include folder, {OutDir, "Ebin"} percent to specify the compiled beam file directory]}.2, write the co

Questions:When we put all the supervision tree in a project through a simple function game:start (), we find that the tree structure is particularly complex, with only one root node, and then it expands.Here, this is why application appears, designing a sub-block (application) that can be switched on at any time. For example: In the Log app, DB app, game app, connect app.So the switch management of these applications is very convenient, "Imagine if you use supervisor, the runtime also to manuall

Here is an elang description: Erlang Quick Start Abstract: Erlang is not only a programming language, but also has some features closer to the operating system than the programming language: concurrent threads, Job Scheduling, memory management, distributed, and networking. It has a super lightweight process, which dynamically changes the memory requirements. Erlang
