A guide to the erlang source.

Contents

Download

The source can be downloaded from: http://erlang.org/download.html or http://github.com/mfoemmel/erlang-otp/tree/master

Tree

Most of the interesting code is in: erts/emulator/beam

Atoms

The atoms used in erlang are listed in erts/emulator/beam/atom.names and are referenced in the code as am_foo. So the 'EXIT' atom is am_EXIT in the code.

Types

Most used types are: Sint, Uint, Eterm, ... Conversion is done in erts/emulator/beam/big.c. For example uint_to_big(Uint x, Eterm *y). term_to_Uint(Eterm term, Uint *up)

Scheduler

The process struct is defined in erts/emulator/beam/process.h. The important function is Process *schedule(Process *p, int calls) in process.c . The next process is picked in "pick_next_process" of that method.
