Let me correct myself:
The supervisor documentation is correct. (The supervisor has no other
requirements on the start function for a child process than that
it creates and links to it as described.)
However the gen_server|fsm|event man pages are not.
It says "A gen_server started using start_link is linked to the
calling process, this function must be used if the gen_server is
included in a supervision tree." which gives the impression that
the only difference between start and start_link is the linking,
which it is not, as Ulf described.
These man pages have now been corrected.
Best regards, Gunilla

I don't mean to argue with the OTP team but the supervisor docs say, when
describing children specifications:
|StartFunc defines the function call used to start the child process. It should
be a
|module-function-arguments tuple {M,F,A} used as apply(M,F,A).
|
|The start function must create and link to the child process, and should return
|{ok,Child} or {ok,Child,Info} where Child is the pid of the child process and
Info an
|arbitrary term which is ignored by the supervisor.
