a new api
« on: March 05, 2002, 06:59:44 AM »
the first byte/char would identify what we are in front of
at the moment i planned

PS_DATA  = 01;  // posting datas
PS_EVENT = 02;  // event notification
PS_ACK   = 03;  // ack to client request (error code)
PC_GET   = 04;  // asking data
PC_CMD   = 05;  // exec command
PC_EVENT = 06;  // event notification

ok, i updated this doc above
i'm sure it's not so readable, it needs a big effort, but at the moment is mainly for my own use.
however, i would like to see comments, but probably i will see none :rolleyes:

maybe in a week i will get something working and then i will receive feedback

a new api

Here're what I want for the new API:

We (future plugin coders) must be able to create one DLL which will be put in PLUGINS directory (or whatever) and activated in &RQ configuration..

Plugins must have mainly entry and exit function calls, which will be called when activated/deactivated.

Plugins must have something called something like TYPE which tells the type (heh, not surprising?) of the plugin. To be more precise, some of the plugins must not be active in the same time. Take an history plugin.. Say there are two history plugins.  They must not work together, not to overlap. :)

Well, I have more to write, soon.

i will add such a feature if it will be needed

i decided to create a new api for plugins
it will be base on a single string, so it will easily fit both dde and dll system

still not sure what system will be used, both? :)
