// User-friendly wrappers around select().
// Take various numbers of file descriptors and an optional timeout.
// Naming scheme is "r" for "readable", "t" for "timeout".
// i.e. select_rr waits for either of two fds to be readable.
// The return value is the file descriptor that has become useable,
// i.e. select_rr(4,9) can return 4 or 9.  If the timeout expires,
// -1 is returned.  -2 can also be returned but I can't recall when.

int select_r (int fd1);
int select_rr(int fd1, int fd2);
int select_rt(int fd1, float timeout);
