io_eagain - tell io_wait that you got an EAGAIN
#include <io.h> void io_eagain(int64 fd);
If io_wait() said that you can read from a descriptor, you try to read from it, and you get EAGAIN, you need to tell io_wait(). This is important for edge triggered event notification schemes like Linux 2.4's SIGIO, or you will lose events. io_tryread(), io_trywrite() and io_sendfile() and iob_send() already take care of this for you. This function is only of interest if you integrate io_wait() with legacy code that uses read/write directly.
