[Asterisk-Users] Howtos on writting applications or modules ?

    There isn't really any hard core documentation, but I think you can run
'make progdocs' and get some stuff. Everything I've learned/needed to learn
about the API I have learned from reading the code to other modules/apps.

    Got no clue on that. Most of the modules/apps I've written/patched are
loaded by issuing 'load <mod name>.so" on the CLI. Most modules/apps are
loaded and then something triggers asterisk to execute the main routine of
that module/app (the name of that routine is set when the mod/app is
registered).

    everything inside apps/

    I don't believe you can share resources across modules like that. For
instance, if I have two seperate apps that both connect to database, I do
not believe (nor think it wise) to share a connection handler between them.
