[Gaim-devel] How to start making a plugin

[<nd...@gm...>]

I will write a simple plug in.
When a message is received the it must send a "5" to the serial port.
I in HowTo in the source packed there is a note that this how to is very old.
So i have try to make a plug in based on the sample.c file in the source.
but this will not compile.

In Function »plugin_load«:
error: `true' undeclared (first use in this function)

where can i find some more good docs?
