Alternate NXC API

Post by mrblp »

Hello all,

When I started coding some small programs for the NXT in summer 2010 I always had a look in the great online manual of John's NXC. Some times I had to look a lot because I always forgot the names of the interface functions and / or constants.

These days I started again with a small program and I thought - the API seems to me - well - growed. But I am missing a system in the naming - sorry John. I do not know all of the history...

Today I started an "alternate API". This is nothing magic - there are mostly the same constants and functions just with another naming. Things work exactly as the original API functions because this is just a header file. So of course the original API still works with it.

Here I use "Out" or "OUT_" as prefix for the module API, "Set" or "SET_" as prefix for functions which are setting / writing data, "Rst" or "RST_" for functions which are resetting data and "Get" or "GET_" as prefix for functions which are getting / reading data. There are some other naming conventions which should be clear by reading the file. For making it really complete I have to add some (doxygen style) comments - perhaps Johns originals changed to the new API names - if he allows me to use them.

If anybody is interested in this I can work further on this and all of you are invited to work with me :-) If not then I know I only do it for me.

So here we are, the first module is the output module:
