Hiding data between C modules.

Hello,
I want to be able to specify a main module which contains my main() function in main.c. I then want to be able to be able to implement some other function in another module, made up of module1.c, and the declaration of the function in module1.h. I should be able to get at the function, by including module1.h in my main.c file, and then accessing the function in module.c from my main function.

I should be able to do this, certainly in C++, but is this not available to me in C?

Cheers,

Rob Wilson

The CCS software does not have a linker like C++ (or HiTech) so you have to <INCLUDE> all your modules/submodules in MAIN.C somewhere.

However, you can <include> them at the end of MAIN.C and use the standard prototype (or an .H file with the prototypes) at the start if you dont want them all up front.

I've just read this reply, and my heart sank. I have never come across such a serious limitation in a compiler tool set. Oh, well, CANDO.

Golly - This is a PIC with very limited resources, not some PC with 512 megs of RAM. You can relocate 20 megs of program space nearly anywhere in 512 meg of ram. On a PIC when every bit counts it's not such a wise thing to do.

I like the simple/straightforward way that this compiler works - no funny business going on behind my back.
