Hello managers,

is getlogin(2) broken under du-4.0b???

I have a small c-programm,

  #include <unistd.h>
  main() {
    char *val;
    val = getlogin();
    if ( val == (char *)NULL ) {
      perror("getlogin(2) failed");
    } else {
      printf("getlogin(2): login name = %s\n", val);
    }
  }

which runs under du-4.0a and returns the loginname,
while under du-4.0b an error is returned:

    getlogin(2) failed: Invalid argument


Obviously i've missed something? What's the problem here?

Thank you!
