io_dontwantread - Man Page

#include <io.h>

void io_dontwantread(int64 fd);

io_dontwantread tells the next io_wait() that you don't want to read from this descriptor for now.  Call io_wantread() again if you change your mind.

You have to have called io_fd on the descriptor first (io_pipe and io_socketpair do this for you).  Waiting on descriptors only works for sockets, fifos and pipes.  It may also work on devices and TTYs, but that is platform dependent -- you should not rely on that.
