return of char* function

The first one is incorrect as you return a pointer that points to nowhere if test is false; it will work reliably if you return NULL

char* myFunction1(boolean test) //Function 1
{
  static char variable[10];

  if(test)
  {
    strcpy(variable, "something");
    return variable;
  }

  return NULL;
}

void loop()
{
  char *result = myFunction1(false);
  if(result == NULL)
  {
    // no result returned
  }
  else
  {
    // result returned
  }
