I have defined a type to close a file automatically when it goes out of scope:
class auto_close
{ int stored_fd;
public:
auto_close (int fd) { stored_fd = fd; }
~auto_close () { int e = errno; close (stored_fd); errno = e; }
};
Now, after opening a file:
fd = open ("file", 0)
I declare one of these:
auto_close my_close (fd);
The only problem is I have to think up a name (my_close) which I never use. Is
there any way to get away with not having to think up a name? If there isn't,
I think there should be!
