[Freeswitch-dev] Create applications in FreeSWITCH

[Steven Ayre]

If you're looking for help on writing new applications then of course
everything under src/mod/applications/*/ provide good examples.

There's also some documentation online of the APIs available to you
within FreeSWITCH:
http://docs.freeswitch.org/

In particular I recommend you look at the following sections
Modules -> Brought To You By APR
Modules -> Core Library

Core Library will tell you the APIs for interacting with
sessions/channels (calls) and provide you with useful interfaces for
doing may useful things like DB access, hash tables, file access etc,
while APR gives you a platform independant way of doing things like
like memory allocation, network access, threading etc. Using them will
save you much of the work and keeps the program style nicely
consistent across FreeSWITCH. Done right your module should also work
on any platform FS runs on without any changes needed (unless you app
depends on something that really is platform-specific such as loading
a DLL file on Windows).
