int reset (int t)

Reset the underlying fd.

Optionally takes a value to reset the underlying fd to. If no

value is passed, underlying fd will be set to an invalid value.

If the fd_ is not set to InvalidValue(), calls close(2) on the fd and

returns any error value. Otherwise, returns -1.

int * reset_and_get_address ()

Reset the underlying fd, and then get the address of the underlying internal fd storage.

Note: The intended purpose is to facilitate interactions with C APIs which expect to be

provided a pointer to a handle used as an out parameter.
