ahhh, noob question.

I'm using DevC++ and im trying to call a function that is written in another '.c' file that is included in the project

umm heres an example of what im trying to do.



~MAIN.C~

Code:

---

#include <stdio.h>
#include "func.c"

int main()
{

    callprint("hello world!");
   
getchar(); 
    return 0;
   
}//end of main

---

~FUNC.C~

Code:

---

#include <stdio.h>

void callprint(char text[])
{
printf(text);             
}

---

it keeps comming up with multi definition of callprint(char text[])

You never include .c files, you include .h files.
func.h:

Code:

---

#ifndef __FUNC_H__
#define __FUNC_H__

void callprint(char text[]);

#endif

---

func.c:

Code:

---

#include <stdio.h>

void callprint(char text[])
{
    printf(text);             
}

---

main.c:

Code:

---

#include <stdio.h>
#include "func.h"

int main()
{
    callprint("hello world!"); 
    getchar(); 
    return 0;
}//end of main

> it keeps comming up with multi definition of callprint(char text[])
That's because you #include the source code (that's one copy), and you also compile it as a separate file (that's two).

Do as rags_to_riches says and create a header file.

Oh, and
printf(text);
is extremely dangerous.
If you make the mistake of passing a string with formats (like %d), then the call to printf becomes undefined (no extra parameters you see).

Use fputs() in this instance, or perhaps
printf("%s",text);
