No. It prints:
print1
print2
It should print:
print1
print2
print2

This is what I want to do:

#include <stdio.h>

typedef void (*funcptr)();

void test_print1()
{
  printf("print1\n");
}

void test_print2()
{
  printf("print2\n");
}


void eval_ptr(funcptr *a)
{
  while (*a != NULL)
  {
    (*a)();
    a++;
  }
}

int main ()
{
  funcptr ep1[3] = {test_print1, test_print2, NULL};
  funcptr ep2[2] = {test_print2, NULL};
  eval_ptr(ep1);
  eval_ptr(ep2);
  return 0;
} 

But i need it in one function with two entry point. I can code this in assembly, but not in C
