Okay, I understand now. Thanks.

I understand. But what about the function prototype?

Thanks, there were some obvious problems there - most shamefull, thanks for pointing them out.

But I don't understand why I would pass the file pointer as a non-pointer. Why?

I see. Should I pass is as so:

write (**OutfilePtr, Chargroup);

And take away the const declaration in the prototype?

Of course. I'm sorry.

I've pinpointed the problem to the write functions. The compiler says there's a parse error on lines with Chargroup or filepntr.

Hi, I'm having another episode with function parameters, but I've included the source files.

Thanks for your help.


/* Write - This module writes an array of 60 converted characters into */...

I've always kept my function bodies in .h files and included them as modules in my main.c file. I understand this is bad practise. Do I declare the function prototype in the header file, and then use...

So, is it good practise to prototype your functions in header files? I've gotten away with it enough.

a.h:

void function();


a.c
void function(int *parameter)
{

What's the difference between a .c file and a .h file? I though .h was just for modules, but I hear people calling it header files. Also, everyone seems to have .h .c files for each module.

What's...

Thanks alot for your answers!

That's cool, but I wanted to invert the letters. Ie. A becomes Z, b becomes y.
You know what I mean?

Hi,

I want to invert some ASCII characters, ie, A becomes Z, z becomes A, etc.

Would anyone be able to point me to a simple ASCII chart or give me some suggestions?

Thanks,

I see, that's a good point. I actually thought that EOF was a special character, but I see it's a macro.

Thanks again.

Yeah, cheers mate, that did the trick.

Ah, it's amazing, a few weeks ago I thought I knew it all with C, but these dynamic parameters are a totally new challenge for me, and yet again, it's the...

I haven't tried it yet (on another machine), but I think you've hit it spot on.

Thanks!

It doesn't seem to answer my questions. See, I can't see what I'm doing wrong. I passed the parameter as a pointer to a pointer, I gave the function the address, why would it be giving me an...

Thanks for the help. The functions for opening my files now run as sweet as a nut! :D

I've encountered a similar problem though. When I try to use a double pointer for a function that reads the...

So, in theory it's used as:

int Variable;
int *Pntr;
int **Pntr2Pntr;

Pntr = &Variable;
Pntr2Pnr = &Pntr;

Okay, thanks alot.

I know this sound's very stupid, but I'm not quite aware what two stars mean. Is that a pointer to a pointer? or what?

Thanks.

Hey,

I'm trying to pass some file pointers as function parameters but I'm having a little trouble with it.

Say, I pass the pointer to a function to open my file:

openF(&FilePntr, argv);
