Subject: Multi-modules
For my multi module programs, I declare global variables (like your
pointers) in the source file that contains the program's main() function.
Then, to make there variables globally visible, I create a .H file that
contains their prototypes as "extern" and then I include this .H file in ALL
the modules of the program that must have access to the global variables.
Like this:
Program consists of main.c mod1.c mod2.c and the .H vars.h- with the int
"loop" that has to be accessible in all three, i. e. totally global to the
whole program:
[main.c]
#include "vars.h"
int loop, loop2;
int main()
{
.
.
.
}
[mod1.c]
#include "vars.h"
void test()
{
loop = 1;
}
[mod2.c]
#include "vars.h"
void test2()
{
loop2 = 1;
}
[vars.h]
extern int loop,loop2 /*Defined in main.c, declared here to globally
accessible in all modules*/
Hope this helped!
Kind Regards,
Rylan
