That's right, because you're passing second character of tausta string
(zero-based 1) which happens to be int (characters are of type int).

Thus, for your program to work, you should create array of string
pointers (just like argv) and pass it to displaypcx:

char* tausta[] = {"tausta.pcx"};

int main(void)
{
  displaypcx(sizeof(tausta), tausta);
}

Hope this clears your problem.
