I have a piece of code which sets subroutines to be called on certain
events:
$cl->reg_cb(
session_ready=>sub { sessionReady(@_); },
disconnect=>sub { disconnect(@_); },
error=>sub { error(@_); },
message=>sub { messageReceived(@_); }
);
I want this in a module. However, I want sessionReady() et al to be in
the calling code. Is there a way I can either have the module be okay
with this, and know that these subroutines will be present in the
calling code, or a way I can pass the subroutines to the module with
something like
setup(&sessionReady, &disconnect, &error, &messageReceived);
?
