Return value should be as bool type as this function declaration,

Actually, bool return values are in general a bad idea if you mean
success/fail, especially if you can use POSIX error codes such as in
this case ENOENT.
Yeah.
I've sent a patch that changes the return value to int.
Cool! I just have two minimal comments inline.
Thanks
