[erlang-questions] What is the function be defined as BIF?

Tue Nov 27 08:17:49 CET 2007

I found that i lose some word in the code.

start(Name,Mod)->register(Name,spawn(fun()->loop(Name,Mod,Mod:init()) end)).


Why  the code can be compile?
start(Name,Mod)->erlang:register(spawn(fun()->loop(Name,Mod,Mod:init()) end)).

  start(Name,Mod)->register(spawn(fun()->loop(Name,Mod,Mod:init()) end)).

  Eshell V5.5.5  (abort with ^G)
  ./genserver.erl:4: function register/1 undefined

  modify the register to  erlang:register
  start(Name,Mod)->erlang:register(spawn(fun()->loop(Name,Mod,Mod:init()) end)).

  10> c(genserver).

  The register function is BIF ? 
  And the spawn function is BIF? 
  All of erlang:* is BIF?
  When we need specify a prefix erlang:* ?
  Why the most of example does not using erlang:register?
