How lib_chan Works

lib_chan is built using code in four modules.

  • lib_chan acts as a “main module.” The only routines that the programmer needs to know about are the routines that are exported from lib_chan. The other three modules (discussed next) are used internally in the implementation of lib_chan.

  • lib_chan_mm encodes and decodes Erlang messages and manages the socket communication.
