you make a .h header file defining the pointer as extern, which you then
include within your .c file thus making it accessable.

e.g.

within prog1.h
==============
typedef struct {
  int i;
  char* j;
} T_example_S;

typedef T_example_S* T_example_P;

extern T_example_P p;
/*-----------------------------------------*/
within prog1.c
==============
T_example_P p;

void function1(void)
{
  p->i = 12;
}
/*-----------------------------------------*/
within prog2.c
==============
#include "prog1.h"

void function2(void)
{
  switch (p->i)
  {
    case 12: p->j = "Function 1 was already called.\n"; break;
    default: p->j = "peulengaleis rules.\n"; break;
  }
}
/*-----------------------------------------*/

Good Luck !!!
